Exploring the Intricacies of Genetics through DNA

Introduction The hereditary molecule that is tasked with carrying genetic instructions that are used in all living things in development, growth, reproduction and functioning is referred to as deoxyribonucleic acid (DNA). DNA molecules consist of two strands which are bipolar and are mostly coiled near to one another to form a spiral. This strands are referred to as polynucleotides simply because they are made of small units known as nucleotides. The information of the DNA is stored in this nucleotides. […]

The Physiology and Genetics Behind Alzheimer Disease

Alzheimer disease is a progressive and ultimately fatal brain disorder, in which communication between cells are halted and eventually lost. It is the most common form of dementia, and is generally (though not exclusively) diagnosed in patients over the age of 65. As communication amongst neurons is lost, symptoms such as inability to recall memories, make appropriate judgment, and proper motor function are lost and worsen over time. Affecting an estimated 2.4 million to 4.5 million Americans, with the number […]

How Epigenetics May Affect Alzheimer’s Disease

Abstract Alzheimer's disease (AD) is a neurodegenerative disease affecting approximately 5.5 million people. Each year, more and more information is uncovered about AD and, recently, studies are attempting to validate the hypothesis that epigenetics significantly affects AD pathology. Recognizing the need for these studies the National Institute on Aging and Alzheimer's Association (NIA-AA) published a new research framework in an effort to redefine the disease based on biological marker, as opposed to syndromal markers. This review considers two published works, […]

Technology Evolution: Insights into Invisible Evolution and Epigenetics

From Divine Creation to Early Evolutionary Theories: Lamarck, Darwin, and the Quest for Understanding Until the eighteenth century, the general idea of how the world came to be was rooted in a Creator uniquely forming each type of species (Futuyma, 2017). The idea tended to be based on the Bible and the Christian faith. Many people believed a supreme being created the Earth and each different species, the species remaining unchanged throughout time. During the eighteenth century, several different scientists […]

What is Mitosis?

Mitosis is a complex division of a single cell, known as the ""mother"" cell, into two genetically similar cells, known as ""daughter"" cells. During this process the nuclear chromatin (located in the cell's nucleus and containing the DNA of the cell) is duplicated, and then split, creating 46 chromosomes(92 chromatids) for each of the ""daughter"" cells. The process of mitosis is made up of phases, sometimes including the preparation of the cell for division, interphase, while always including prophase, metaphase, […]

Genetics and Personality

In my initial position paper, I said that the past, present, and future is very important to personality. In addition, I theorized that it is important that we understand that the present is influenced by experience form the past; the present is influenced by one’s thought of the future; the concerns of the past and the future can be the result of one’s personality. Currently, I believe these theories are true but, they are not always accurate when predicting how […]

GMO Food Labeling

Genetically modified organisms, also known as GMO, are organisms that have been genetically altered to have a specific characteristic or trait. GMOs were first introduced in 1994 and no one knew about the potential health problems that could come. Nowadays more Americans worry about where their food comes from. Even though GMOs can help starvation and save labor costs, GMOs should be labeled because we don't know the long-term health effects, and GM foods can cause a numerous amount of […]

Right from the DNA structure discovery, a lot more has come out into the open. There are so many genetics research topics to choose from because of the wide scope of research done in recent years.

Genetics is so dear to us since it helps us understand our genes and hereditary traits. In this guide, you will get to understand this subject more and get several topic suggestions that you can consider when looking for interesting genetics topics.

Writing a paper on genetics is quite intriguing nowadays. Remember that because there are so many topics in genetics, choosing the right one is crucial. It will help you cut down on research time and the technicality of selecting content for the topic. Thus, it would matter a lot if you confirmed whether or not the topic you’re choosing has relevant sources in plenty.

What Is Genetics?

Before we even go deeper into genetics topics for research papers, it is essential to have a basic understanding of what the subject entails.

Genetics is a branch of Biology to start with. It is mainly focused on the study of genetic variation, hereditary traits, and genes.

Genetics has relations with several other subjects, including biotechnology, medicine, and agriculture. In Genetics, we study how genes act on the cell and how they’re transmitted from a parent to the offspring. In modern Genetics, the emphasis is more on DNA, which is the chemical substance found in genes. Remember that Genetics cut across animals, insects, and plants – basically any living organism there is.

Tips On How To Write A Decent Research Paper On Genetics

When planning to choose genetics topics, you should also make time and learn how to research. After all, this is the only way you can gather the information that will help you come up with the content for the paper. Here are some tips that can bail you out whenever you feel stuck:

Choosing the topic, nonetheless, is not an easy thing for many students. There are just so many options present, and often, you get spoilt for choice. But note that this is an integral stage/process that you have to complete. Do proper research on the topic and choose the kind of information that you’d like to apply.

On the web, there’s a myriad of information that often can become deceiving. Amateurs try their luck to put together several pieces of information in a bid to try and convince you that they are the authority on the subject. Many students become gullible to such tricks and end up writing poorly in Genetics.

The term ‘gene’ was coined by Danish botanist Wilhelm Johannsen in 1909. It is the basic physical and functional unit of heredity. Heredity is the transfer of characters from parents to their offspring that is why children resemble their parents. A hereditary unit consists of a sequence of DNA (except in some viruses that contain RNA, instead) that occupies a spe­cific location on a chromosome and determines a particular characteristic in an organism. DNA is a vast chemical information database that carries the complete set of instructions for making all the proteins that a cell will ever need.

Each gene contains a particular set of in­structions, usually coding for a particular protein. Genes achieve their effects by directing protein synthesis. The sequence of nitrogenous bases along a strand of DNA determines the genetic code. When the product of a particular gene is needed, the portion of the DNA mole­cule that contains that gene splits, and a complementary strand of RNA, called messenger RNA (mRNA), forms and then passes to ribosomes, where proteins are synthesized.

A sec­ond type of RNA, transfer RNA (tRNA), matches up the mRNA with specific amino acids, which combine in series to form polypeptide chains, the building blocks of proteins. Experi­ments have shown that many of the genes within a cell are inactive much or even all of the time, but they can be switched on and off.

DNA resides in the core, or nucleus, of each of the body’s trillions of cells. Every human cell (with the exception of mature red blood cells, which have no nucleus) contains the same DNA. Each human cell has 46 molecules of double-stranded DNA. Human cells contain two sets of chromosomes, one set inherited from the mother and one from the father. (Mature sperm and egg cells carry a single set of chromosomes). Each set has 23 single chromosomes – 22 autosomes and an X or Y sex chromosome. (Females inherit an X from each parent, while males get an X from the mother and a Y from the father.) In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases.

The Human Genome Project has estimated that humans have between 20,000 and 25,000 genes. Every person has two copies of each gene, one inherited from each parent. Most genes are the same in all peo­ple, but a small number of genes (less than 1 percent of the total) are slightly different between people. Alleles are forms of the same gene with small differences in their sequence of DNA bases. These small differences contribute to each person’s unique physical features. Genes carry information that determines the traits, the characteristics we inherit from our parents. The branch of biology that deals with heredity, especially the mechanisms of heredi­tary transmission and the variation of inherited characteristics among similar or related organisms is known as genetics.

2. Essay on Mendelian Genetics :

Sir Gregor Johann Mendel (1822 to 1884) was Austrian monk who used garden pea (Pisum sativum) for his experiments and published his results in 1865. His work, however, was rediscovered in 1900, long after Mendel’s death, by Tschermak, Correns and DeVries. Men­del was the first to suggest principles underlying inheritance. He is regarded as the founder or father of genetics. He developed the concept of the factors to explain results obtained while cross breeding strains of garden peas. He identified physical characteristics (phenotypes), such as plant height and seed colour, which could be passed on, unchanged, from one generation to another.

The hereditary factor that predicted the phenotype was later termed a “gene”. The genetic constitution of an organism is known as genotype. Mendel hy­pothesized that genes were inherited in pairs, one from the male and one from the female parent. Plants that bred true had inherited identical genes (homozygotes) from their parents, whereas plants that did not breed true inherited alternative copies (hybrids, or heterozygotes) of the genes (alleles) from one parent that were similar, but not identical, to those from the other parent.

Alleles are the alternative forms of the same gene which determine contrasting characters. One chromosome might contain a version of the eye colour gene that produces blue eyes, and other chromosome might contain a version that produces brown eyes. If an individual has both versions of the gene, the individual is heterozygous for the eye colour trait. If an individual has the same version of the eye colour gene on both chromosomes, the individual is homozygous for the eye colour trait. In case plants the allelic character of height are the tall (T) and dwarf (t).

Alleles are one alternative of a pair or group of genes that could occupy a specific posi­tion on a chromosome. Genes are composed of sequences of nucleotides, and a variation in this sequence can affect the protein made from that gene. A change in the manufacture of a protein in an organism often leads to an observable result. There are many different alleles for the gene that manufactures protein to give humans their unique eye colour. There are two alleles for flower colour in the common garden pea.

Some of these alleles had a greater effect on the phenotypes of hybrids than others. For example, if a single copy of a given allele was sufficient to produce the same phenotype seen in homozygous organisms, that gene is termed a “dominant”. Conversely, if the allele could only be detected in the minority of the offspring of hybrid parents that were homozygous for that “weaker” allele, the gene is termed a “recessive”. Dominant and recessive are relative terms. Consider a plant with a gene for red flower colour and a gene for blue flower col­our.

This plant bears red flowers, although it has a gene for blue flower colour, too. Red flower colour is the dominant trait, while blue flower colour is the recessive trait. The red colour gene in a sense overpowers the blue colour gene. In order for the plant to have blue flowers, it would need to completely lack the gene for red flower colour. Dominant traits are normally represented by uppercase letters, such as R. The corresponding recessive trait would be represented by a lowercase letter, r. A plant with genotype Rr will have red flow­ers, as would a plant with genotype RR. But a plant with genotype rr would have blue flow­ers.

Mendelian genetics, also known as classical genetics, is the study of the transmission of inherited characteristics from parent to offspring. Gregor Mendel actually calculated the ra­tios of observable characteristics in the common garden pea plant Pisum sativum. Mendel studied seven characteristics in peas including seed texture, seed colour, flower colour, flower position; stem length, pod shape and pod colour (Fig. 6.1). Peas were a good model system, because he could easily control their fertilization by transferring pollen with a small paintbrush.

This pollen could come from the same flower (self-fertilization), or it could come from another plant’s flowers (cross-fertilization). Because the seven pea plant charac­teristics tracked by Mendel were consistent in generation after generation of self- fertilization. These parental lines of peas could be considered pure-breeders (or, in modern terminology, homozygous for the traits of interest). Mendel and his assistants eventually de­veloped 22 varieties of pea plants with combinations of these consistent characteristics. He applied mathematics and statistics to analyze the results obtained by him.

Seven Pairs Characters Used by Mendel in his Work

Mendel started his pea breeding program by allowing certain pea plants to repeatedly self-fertilize. Peas are able to fertilize their own flowers which are called selfing. If pea selfing continues over many generations the pea plants will be homozygous or have an identical pair of genes for a certain characteristic. These plants will contain either two identical reces­sive genes (homozygous recessive) for a characteristic or two identical dominant genes (homozygous dominant) for the same characteristic and are considered pure-breeding for those characteristics.

For example, purple flower colour in peas is dominant and white flower colour in peas is recessive. When a white flowered (homozygous recessive) pea plant is crossed with a purple flowered (homozygous dominant) pea plant, the resulting offspring all has purple flower colour.

The gene composition (genotype) for the flower genes in each of these types of pea plants is represented as shown below:

Mendel used characteristics of pea plants and four o’clock flowers (Mirabilis jalapa) to analyze the hereditary patterns of these traits. His historic experiments led him to the con­clusion that inherited characteristics were carried in discrete, independent units (later named genes). In Mendel’s interpretation, hereditary characteristics occurred in pairs of factors that had specific relationships. Mendel first crossbred one tall, true-breeding plant with one short, true-breeding plant.

Contrary to the blending theory, all the offspring were tall. In terms of genotype, the original tall plant was TT (two dominant alleles; homozygous), the short plant was tt (two recessive alleles; homozygous), and the second-generation plants were Tt (one dominant and one recessive allele; heterozygous). When Mendel next allowed these plants to self-fertilize, he found that the short trait reappeared in the third generation. The ratio of short to tall plants was almost exactly 3:1. Their genotypes were as follows -1 short (tt) : 2 tall (Tt): 1 tall (TT). Based on these observations (Fig. 6.2), Mendel formu­lated a series of laws that are the basis of what we now term “Mendelian” inheritance pat­terns.

ADVERTISEMENTS: (adsbygoogle = window.adsbygoogle || []).push({}); 3. Essay on the Punnett Square :

Mendel worked by observing characteristics (phenotypes) and calculating the ratios of each type to form his principles of inheritance. However we can predict the ratios of phenotypes by using Mendel’s principles. One of the most common methods of determining the possible outcome of a cross between two parents is called a Punnett square. To perform a Punnett square one must first figure out all the possible combinations of the alleles to be studied for each parent.

The possible gametes for one parent go on the X axis and the possible gametes for the other parent go on the Y axis (one allele in each cell of the upper row (traditionally the mother) and rightmost column (traditionally the father). The gamete combinations are then paired in the squares below and to the side of each type, i.e. the offspring’s genotypes are then calculated by observing the intersection of the mother’s and father’s individual alleles (much like a multiplication table).

Punnett Square for a Monohybrid

Eye colour in human is much more complex. A mother and father, both having the brown eye phenotype, have a child. We know that both parents carry the gene for blue eye colour and therefore are heterozygous for this trait. These parents can either donate a dominant B to the gamete or a recessive b to the gamete (Fig.6.3).

The outcome of this cross shows that 3 times out of 4 (75%) the child will have brown eyes and 1 out of 4 times the child will have blue eyes (25%). The probability that the child’s genotype will be heterozygous, for eye colour alleles, is 50%. The probability is 25% for either the homozygous recessive or dominant genotype.

X-linked characteristic: colour blindness in human

There are several known X-linked characteristics in humans but few, if any, Y-linked char­acteristics are usually reported. Females have two X chromosomes with one or the other X chromosome remaining active in a mosaic pattern in a tissue. Males have only one X chro­mosome so if the X chromosome of a male has a defective allele there is no companion X chromosome to compensate for the deficiency. A female must have the same defective allele on both her X chromosomes to demonstrate any deficiencies (Fig. 6.4).

Punnett Square for the X-Linked Characteristic Colour Blindness

4. Essay on the Mendelian Principles :

During Mendel’s time DNA had not been identified as the substance of heredity and it was unknown how offspring obtained certain characteristics from their parents. Since Mendel’s work elucidated dominant and recessive characteristics his study supported the particulate theory of inheritance. Mendel accomplished this work by calculating the ratios of observable characteristics of the offspring from known parental types.

The first parental types were ho­mozygous recessive and homozygous dominant pure breeding types. The parental generation or P generation, by definition, is always homozygous recessive and homozygous dominant for the traits to be studied. The offspring which results from the mating of parental types (P generation) will always be heterozygous for the characteristic.

a. Mendel’s Law of Dominance:

The first law of Mendel states that “In a cross of parents that are pure for contrasting traits, only one form of the trait will appear in the progeny, in other words factors retain their identity from generation to generation and do not blend in the hybrid”. In other words it says that, if two plants that differ in just one trait are crossed, then the resulting hybrids will be uniform in the chosen trait. Depending on the traits is the uniform features either one of the parents’ traits (a dominant-recessive pair of characteristics) or it is intermediate.

When two pure breeding organisms of contrasting characters are crossed, only one character of the pair appears in the F1 generation, known as the dominant character (example- tallness) and the other unexpressed or hidden character is known as the recessive character (example- dwarfness). When Mendel crossed a true breeding red flowered plant with a true breeding white flowered one, the progeny was found to be red coloured. The white colour suppressed and the red colour dominated.

Mendel’s law of dominance is generally true, but there are many exceptions to the law. For each of the seven pairs of characters examined, it was observed that one allelomorph dominated over the other, so that F1 exhibits one or the other alternative phenotypes repre­sented in the parents. Some inherited traits do not exhibit strict Mendelian dominant/ recessive relationships. The simplest example of this phenomenon is called codominance, or incomplete dominance.

This pattern is displayed in the colours of four o’clock flowers. When a white and a red flower are cross-fertilized, the second generation is all pink. How­ever, when a pink flower is allowed to self-fertilize, the white and red attributes return. The colour ratios for this third-generation cross are – 1 white: 2 pink: 1 red. This pattern is due to the fact that three alleles, instead of the usual two, determine colour in four o’clock flow­ers. If red colour is designated R and white colour r, then pink colour (not red or white) is the phenotypic effect of genotype Rr. (This is one type of pattern formerly used in support of the blending theory of inheritance). Thus in certain cases the hybrid offsprings resemble one parent much more closely than the other but does not resemble it exactly, so the domi­nance is incomplete. This is termed as incomplete dominance (Fig. 6.5).

Incomplete Dominance

Another example of codominance is the ABO blood typing system used to determine the type of human blood. It is common knowledge that a blood transfusion can only take place between two people who have compatible types of blood. Human blood is separated into different classifications on the basis of presence and absence of specific antigens or proteins in the red blood cells.

The protein’s structure is controlled by three alleles; i, IA and IB. The first allele is, i, the recessive of the three, and IA and IB are both co-dominant when paired together. If the recessive allele i is paired with IB or IA, its expression is hidden and is not shown. When the IB and IA are together in a pair, both proteins A and B are present and expressed.

The ABO system is called a multiple allele system for there are more than two possible allele pairs for the locus. The individual’s blood type is determined by which combination of alleles he/she has. There are four possible blood types in order from most common to most rare- O, A, B and AB. The O blood type represents an individual who is homozygous reces­sive (ii) and does not have an allele for A or B (Table 6.2).

Blood Grouping

Blood types A and B are co-dominant alleles. Co-dominant alleles are expressed even if only one is present. The recessive allele i for blood type O is only expressed when two recessive alleles are present. Blood type O is not apparent if the individual has an allele for A or B. Individuals who have blood type A have a genotype of IAIA or IAi and those with blood type B, IBIB or IBi, but an individual who is IAIB has blood type AB.

b. Mendel’s Law of Segregation:

The law of segregations is a law of inheritance proposed by Mendel in 1866. According to this law, “each organism is formed of a bundle of characters. Each character is controlled by a pair of factors (genes). During gamete formation, the two factors of a character separate and enter different gametes”. This law is also called law of purity of gametes. At formation of gametes, the two chromosomes of each pair separate (segregate) into two different cell which form the gametes.

This is a universal law and always during gamete formation in all sexually reproducing organisms, the two factors of a pair pass into different gametes. Each gamete receives one member of a pair of factors and the gametes are pure. That is two mem­bers (alleles) of a single pair of genes are never found in the same mature sperm or ovum (gamete) but always separate out (segregate).The factors of inheritance (genes) normally are paired, but are separated or segregated in the formation of gametes (eggs and sperm), i.e., it states that the individuals of the F 2 generation are not uniform, but that the traits segregate.

Depending on a dominant-recessive crossing or an intermediate crossing are the resulting ratios 3:1 or 1:2:1. This concept of independent traits explains how a trait can persist from generation to generation without blending with other traits. It explains, too, how the trait can seemingly disappear and then reappear in a later generation. The principle of segregation was consequently of the utmost importance for understanding both genetics and evolution.

Monohybrid Cross:

The crossing of two plants differing in one character is called monohybrid cross. Mendel carried out monohybrid experiments on pea plants and based on the results of monohybrid experiment, he formulated the law of segregation. Mendel selected two pea plants, one with a tall stem and the other with a dwarf or short stem. These plants were considered as paren­tal plants (P) and were pure breed. A pure plant is one that breeds true in respect of a particu­lar character for a number of generations. The pure-bred tall and dwarf plants were treated as parents and were crossed.

Seeds were collected from these plants. These seeds were sown and a group of plants were raised. These plants constituted the first filial generation (F1 gen­eration). All the F1 plants were tall and were inbred. The seeds were collected and the next generation (F2) was raised. In the F2 generation, two types of plants were found. They were tall and dwarf. Mendel counted the number of tall and dwarf plants. Of the 1064 plants of F2 generation, 787 plants were tall and 277 plants were dwarf (75% were tall plants and 25% were dwarf plants). Thus the tall plants occurred in the ratio 3: 1 (Fig. 6.6).

Cross between Two Parental Types for One Trait

c. Mendel’s Principle of Independent Assortment:

The Principle of Independent Assortment describes how different genes independently sepa­rate from one another when reproductive cells develop. Mendel formulated the Principle of Independent Assortment from the observations he got from the dihybrid crosses, which are crosses between organisms that differ with regard to two traits.

It is now known that this independent assortment of genes occurs during meiosis in eukaryotes. Meiosis is a type of cell division that reduces the number of chromosomes in a par­ent cell by half to produce four reproductive cells called gametes. In humans, diploid cells contain 46 chromosomes, with 23 chromosomes inherited from the mother, while a second similar set of 23 chromosomes inherited from the father. Pairs of similar chromosomes are called homologous chromosomes. During meiosis, the pairs of homologous chromosome are divided in half to form haploid cells, and this separation, or assortment of homologous chro­mosomes is random. This means that all the maternal chromosomes will not be separated into one cell, while all the paternal chromosomes are separated into another. Instead, after meiosis occurs, each haploid cell contains a mixture of genes from the organism’s mother and father.

Another feature of independent assortment is recombination. Recombination occurs dur­ing meiosis and is a process that breaks and recombines the pieces of DNA to produce new combinations of genes. Recombination scrambles pieces of maternal and paternal genes, which ensures that genes assort independently from one another. It is important to note that there is an exception to the law of independent assortment for genes that are located very close to one another on the same chromosome because of genetic linkage.

Dihybrids Cross between Two Heterozygous Individuals:

A dihybrid cross is a breeding experiment between P generation (parental generation) organ­isms that differ in two traits. Mendel determined what happens when two plants that are each hybrid for two traits are crossed. Mendel therefore decided to examine the inheritance of two characteristics at once. Based on the concept of segregation, he predicted that traits must sort into gametes separately. By extrapolating from his earlier data, Mendel also predicted that the inheritance of one characteristic did not affect the inheritance of a different characteris­tic.

Mendel tested the idea of trait independence with more complex crosses. First, he gener­ated plants that were pure bred for two characteristics, such as seed colour (yellow and green) and seed shape (round and wrinkled). These plants would serve as the Pi generation for the experiment. In this case, Mendel crossed the plants with Round and Yellow seeds (RRYY) with plants with wrinkled and green seeds (rryy). From his earlier monohybrid crosses, Mendel knew which traits were dominant- round and yellow.

So, in the F 1 genera­tion, he expected all round, yellow seeds from crossing these pure bred varieties, and that is exactly what he observed. Mendel knew that each of the Fi progeny were dihybrids; in other words, they contained both alleles for each characteristic (RrYy). He then crossed individual Fi plants (with genotypes RrYy) with one another. This is called a dihybrid cross. Mendel’s results from this cross were present in a 9:3:3:1 ratio. The outcome shows a phenotypic ratio of 9 of the offspring having yellow round peas, 3 having yellow wrinkled peas, 3 having green round peas and 1 having green wrinkled peas. This is a classic 9:3:3:1 phenotypic ratio which is always the result in a dihybrid cross between two heterozygotes with unlinked traits.

The proportion of each trait was still approximately 3:1 for both seed shape and seed colour. In other words, the resulting seed shape and seed colour looked as if they had come from two parallel monohybrid crosses; even though two characteristics were involved in one cross, these traits behaved as though they had segregated independently. From these data, Mendel developed the third principle of inheritance- the principle of independent assortment i.e. alleles at one locus segregate into gametes independently of alleles at other loci. Such gametes are formed in equal frequencies (Fig. 6.7).

Dihybrid Crosses between Two Heterozygous Individuals

Trihybrid Cross:

A trihybrid cross is a breeding experiment between P generation (parental generation) organ­isms that differ in three traits (Fig. 6.8).

Trihybrid Crosses

5. Essay on the Test Cross :

A test cross is a way to explore the genotype, the genetic makeup of an organism. Early use of the test cross was as an experimental mating test used to determine what alleles are pre­sent in the genotype. Consequently, a test cross can help to determine whether a dominant phenotype is homozygous or heterozygous for a specific allele.

Diploid organisms, like humans, have two alleles at each genetic locus, or position, and one allele is inherited from each parent. Different alleles do not always produce equal outward effects or phenotypes. One allele can be dominant and mask the effect of a second recessive allele in a heterozygous organism that carries two different alleles at a specific locus. Recessive alleles only express their phenotype if an organism carries two identical copies of the recessive allele, meaning it is homozygous for the recessive allele. This means that the genotype of an organism with a dominant phenotype may be either homozygous or heterozygous for the dominant allele. Therefore, it is impossible to identify the genotype of an organism with a dominant trait by visually examining its phenotype.

A test cross is the means by which a scientist can determine whether an individual with a dominant phenotype has a homozygous (AA) or heterozygous (Aa) dominant genotype. The test cross involves mating the individual with the dominant phenotype to an individual with a recessive (aa) phenotype and observing the offspring produced. If the individual being tested is homozygous dominant, then all offspring will have a dominant phenotype, since all the offspring will have at least one A (dominant) allele.

7. Essay on the Limitations of Mendelian System :

The simple system of Mendelian genetics is very powerful and serves to explain the inheri­tance patterns of numerous traits. However, many traits are controlled by many genes acting in tandem, and thus do not obey strict Mendelian patterns (although their constituent genes may). Furthermore, many human traits are strongly influenced by the environment as well, and therefore their phenotypes cannot be said to be Mendelian (though the genetic compo­nents may be). In sum, Mendelian patterns are important, but cannot be applied universally. Individual traits must be researched to find out if they obey typical Mendelian patterns.

8. Essay on the Polygenic or Quantitative Inheritance :

When a trait (feature or character) is controlled by a single gene it is termed monogenic inheritance. Many traits or features are controlled by a number of different genes. For exam­ple, the skin colour of humans and the kernel colour of wheat results from the combined effect of several genes, none of which are singly dominant. Polygenes affecting a particular trait are found on many chromosomes. Each of these genes has equal contribution and cumulative the total effect. Three to four genes contribute towards formation of the pigment in the skin of humans.

So there is a continuous variation in skin colour from very fair to very dark. Such inheritance controlled by many genes is termed quantitative inheritance or poly­genic (poly meaning due many genes) inheritance. In polygenic inheritance, each dominant gene controls equally the intensity of the character. The effect of the dominant genes in cumulative and the intensity of character or trait depend upon the number of dominant genes (Fig. 6.10).

Polygenic or Quantitative Inheritance

9. Essay on Multiple Alleles:

Alleles are located in corresponding parts of homologous chromosomes, only one member of a pair can be present in a given chromosome and only two are present in a cell of a diploid. Alleles are genes that are members of the same gene pair, each kind of allele affecting a trait differently than the other. A diploid organism has, by its definition, only two alleles at one time, yet exceptions to the rules do appear. Many examples were found where more than two alternative alleles, also called multiple alleles, are present.

In these cases two or more differ­ent mutations must have taken place at the same locus but in different individuals or at different times. Multiple alleles are alternative states at the same locus. The different alleles of a series are usually represented by the same symbol. Subscripts and superscripts are used to identify different members of a series of alleles. Most alleles produce variations of the same trait, but some produce very different phenotypes.

The most famous example of multiple alleles was discovered in rabbits. It was known that Albino rabbits were produced on occasion in variously coloured rabbit populations. After conducting a monohybrid cross between a coloured and Albino rabbit, it was discov­ered that the members of a pair of alternative genes, either c a or C, must be responsible for coloured or albino rabbits. A cross of homozygous coloured (CC) and albino (c a c a ) rabbits were made and the F1 generation was all coloured, while the F2 generation had three col­oured and one albino. This showed that one pair of alleles was involved, the wild C and the mutant allele c a . It was determined that C was dominant over c a (Fig. 6.11).

Inheritance of Skin Colour

10. Essay on the Chromosomal Theory of Inheritance :

Sutton and Boveri in 1902 observed by that maternal (from mother) and paternal (from fa­ther) character come together in the progeny which is diploid or2n and has chromosomes in pairs and later on segregate during the formation of gametes. The gametes have a single chromosome from each pair and are haploid or n. Chromosomes from two parents come to­gether in the same zygote as a result of the fusion of two gametes and again separate out dur­ing the formation of gametes. Chromosomes are filamentous bodies present in the nucleus and seen only during cell division. The above two observations proved that there is a remarkable similarity between the behavior of character during inheritance and that of chro­mosomes during meiosis.

This led Sutton and Boveri to propose ‘chromosomal theory of inheritance’ and its salient features are as follows:

a. The somatic (body) cells of an organism, which are derived by the repeated division of zygote have two identical sets of chromosomes, i.e., they are diploid. Out of these, one set of chromosomes is received from the mother (maternal chromosomes) and one set from the father (paternal chromosomes). Two chromosomes of one type (carrying same genes) constitute a homologous pair. Humans have 23 pairs of chromosomes.

b. The chromosomes of homologous pair separate out during meiosis at the time of gamete formation.

c. The behavior of chromosomes during meiosis indicates that Mendelian factors or genes are located linearly on the chromosomes. With progress in molecular biology it is now known that a chromosome is made up of a molecule of DNA and segments of DNA are the genes.

Essay on Sex-Linked Characteristics :

In animals the sex is determined by the presence or absence of the Y chromosome. The X and Y chromosomes are not homologous but are completely different chromosomes which carry unique information. No human can exist without at least one X chromosome. There is a viable human phenotype that has one X chromosome and no companion X or Y. These individuals are said to have the Turner syndrome. Turner syndrome (X 0) individuals are females who are of normal to above intelligence and usually have few deficiencies consider­ing their lack of an entire chromosome. One major deficiency of Turner syndrome is sterility and non-development of secondary sexual characteristics.

Certain traits in humans and other organisms can demonstrate sex-linked inheritance of characteristics. This means that the inherited traits are present on the sex determining chro­mosomes the X or the Y. Since there appears to be more information on the X chromosome than on the Y chromosome of humans, most known sex-linked characteristics are actually X- linked characteristics.

In sex-linked traits, such as colour-blindness, the gene for the trait is found on the X chromosome (a sex chromosome). Sex-linked traits affect primarily males, since they have only one copy of the X chromosome (male genotype: XY). Females, who have two copies of the X chromosome, are affected only if they are homozygous for the trait. Females can, however, be carriers for sex-linked traits, passing their X chromosomes on to their sons. Sex-linked inheritance works as follows- if a female carrier and a normal male give birth to a daughter, she has a 1 in 2 chance of being a carrier of the trait (like her mother). If the child is a son, he has a 1 in 2 chance of being affected by the trait. If a female carrier and an affected male give birth to a daughter, she will either be affected or be a carrier. If the child is a son, he will either be affected or be entirely free of the gene.

Another example of a sex-linked trait is haemophilia, made famous by the “Queen Victoria pedigree” of the European nobility. Beginning with Queen Victoria of England (in whom it was probably a spontaneous mutation), the haemophilia gene spread quickly throughout the European rulers (who intermarried as a matter of course). The disease, which prevents blood from clotting properly and renders a minor injury a life-threatening event, claimed several young men of the royal line. Especially since male heirs were pre­ferred over female as successors to the thrones of Europe, the spread of such a debilitating disease was a major problem.

11. Essay on the Linkage and Crossing Over :

The fact behind Mendel’s success was the genes encoding his selected traits did not reside close together on the same chromosome. If they had, his dihybrid cross results would have been much more confusing, and he might not have discovered the law of independent assort­ment. The law of independent assortment holds true as long as two different genes are on separate chromosomes. When the genes are on separate chromosomes, the two alleles of one gene (A and a) will segregate into gametes independently of the two alleles of the other gene (B and b). Equal numbers of four different gametes will result- AB, aB, Ab, ab. But if the two genes are on the same chromosome, then they will be linked and will segregate together during meiosis, producing only two kinds of gametes.

For instance, if the genes for seed shape and seed colour were on the same chromosome and a homozygous double dominant (yellow and round, RRYY) plant was crossed with a homozygous double recessive (green and wrinkled, rryy), the F 1 hybrid offspring, as usual, would be double heterozygous dominant (yellow and round, RrYy). However, since in this example the R and Y are linked together on the chromosome inherited from the dominant parent, with r and y linked together on the other chromosome, only two different gametes can be formed- RY and ry.

Therefore, instead of 16 different genotypes in the F 2 offspring, only three are possible: RRYY, RrYy, rryy and instead of four different phenotypes, only the original two will exist. Notice that the inheritance pattern now resembles that seen in a monohybrid cross, with a 3:1 phenotypic ratio, rather than the 9:3:3:1 ratio expected from the dihybrid cross. If physically linked on a single chromosome, the round and yellow alleles would segregate together, and the wrinkled and green alleles would segregate together, no round green seeds or wrinkled yellow seeds would ever appear.

The above explanation, however, neglects the influence of the crossing over of genetic material that occurs during meiosis. The farther away two genes are from one another, the more likely an exchange point for crossing over will form between them. At these exchange points, the alleles of one gene switch to the opposite homologous chromosome, while the other gene alleles remain with their original chromosomes. When alleles switch places like this, the resulting gametes are called recombinant. In the example above, the original paren­tal gametes would be RY and ry, while the recombinant gametes would be Ry and rY. Thus four different kinds of gametes will be formed, instead of only two formed when the genes were linked (Fig. 6.12).

Gamete Formation

If two genes are extremely close together, crossing over will almost never occur between them, and the recombinant gametes will almost never form. If they are very far apart on the chromosome, crossing over will almost certainly occur between them, and recombinant gam­etes will form just as often as if the genes were on different chromosomes (50 percent of re­combinant). If the genes are at an intermediate distance from each other, crossing over may sometimes occur between them and sometimes not (Fig. 6.13).

Therefore, the percentage of recombinant gametes (reflected in the percentage of recombinant offspring) correlates with the distance between two genes on a chromosome. By comparing the recombination rates of multiple different pairs of genes on the same chromosome, the relative position of each gene along the chromosome can be determined. This method of ordering genes on a chromosome is called a linkage map.

Gamete Formation

12. Essay on Mutations:

Mutations are errors in the genotype that create new alleles and can result in a variety of ge­netic disorders. In order for a mutation to be inherited from one generation to another, it must occur in sex cells, such as eggs and sperm, rather than in somatic cells. The best way to detect a genetic disorder is karyotyping.

i. Autosomal Mutations :

There are certain human genetic diseases which are inherited in a Mendelian fashion such as disease phenotype will have either a clearly dominant or clearly recessive pattern of inheri­tance, similar to the traits in Mendel’s peas. Such a pattern will usually only occur if the dis­ease is caused by an abnormality in a single gene. The mutations that cause these diseases occur in genes on the autosomal chromosomes, the chromosomes that determine bodily char­acteristics and exist in all cells, both sex and somatic, as opposed to sex-linked diseases.

ii. Recessive Disorders :

Genetic disorders are initially arises as a new mutation that changes a single gene so that it no longer produces a protein that functions normally. A disease resulting from a mutation that an allele which produces a non-functional protein will be inherited in a recessive fashion so that the disease phenotype will only appear when both copies of the gene carry the muta­tion, resulting in a total absence of the necessary protein. If only one copy of the mutated allele is present, the individual is a heterozygous carrier, showing no signs of the disease but able to transmit the disease gene to the next generation.

Albinism is an example of a recessive illness, resulting from a mutation in a gene that normally encodes a protein needed for pigment production in the skin and eyes. Many recessive illnesses occur with much greater frequency in particular racial or ethnic groups that have a history of intermarrying within their own community. For example, Tay-Sachs disease is especially common among people of Eastern European Jewish descent. Other well-known autosomal recessive disorders include sickle-cell anaemia and cystic fibrosis.

iii. Dominant Disorders :

Usually, a dominant phenotype results from the presence of at least one normal allele pro­ducing a protein that functions normally. In the case of a dominant genetic illness, there is a mutation that results in the production of a protein with an abnormal and harmful action. Only one copy of such an allele is needed to produce disease, because the presence of the normal allele and protein cannot prevent the harmful action of the mutant protein. Hunting­ton’s disease, which killed folksinger Woody Guthrie, is a dominant genetic illness. A single mutant allele produces an abnormal version of the Huntington protein; this abnormal protein accumulates in particular regions of the brain and gradually kills the brain cells.

iv. Chromosomal Disorders :

Mutation of a single gene results in recessive and dominant characteristics. Some genetic disorders result from the gain or loss of an entire chromosome. Normally, paired homolo­gous chromosomes separate from each other during the first division of meiosis. If one pair fails to separate, an event called non-disjunction, then one daughter cell will receive both chromosomes and the other daughter cell will receive none. When one of these gametes joins with a normal gamete from the other parent, the resulting offspring will have either one or three copies of the affected chromosome, rather than the usual two.

(a) Trisomy:

A single chromosome contains hundreds to thousands of genes. A zygote with three copies of a chromosome (trisomy), instead of the usual two, generally cannot survive embryonic development. Chromosome 21 is a major exception to this rule; individuals with three copies of this small chromosome (trisomy 21) develop the genetic disorder called Down syndrome. People with Down syndrome show at least mild mental disabilities and have unusual physical features including a flat face, large tongue, and distinctive creases on their palms. They are also at a much greater risk for various health problems such as heart defects and early Alzheimer’s disease.

(b) Monosomy:

The absence of one copy of a chromosome (monosomy) causes even more problems than the presence of an extra copy. Only monosomy of the X chromosome is com­patible with life.

(c) Polyploidy:

Polyploidy occurs when a failure occurs during the formation of the gametes during meiosis. The gametes produced in this instance are diploid rather than haploid. If fertilization occurs with these gametes, the offspring receive an entire extra set of chromo­somes. In humans, polyploidy is always fatal, though in many plants and fish it is not.

Meiosis Essays Examples

Meiosis is also called litotes. This is a process by which there occurs cell division. The result is ‘four daughter cells’ with chromosomes that number half of what the parent cell had. This process has two main phases; one, ‘interphase meiosis 1’ and two, ‘interphase meiosis 2. Both these processes are cell division processes. The first interphase involves the cells duplication process while the second interphase involves the crossing over o the divided cells (Belk, 2010).

Introduction, chemical additives and preservatives essay sample, genetically modified essays example, genetically modified essay examples, good essay on proto oncogenes and tumor suppressor genes, 1) proto-oncogenes and tumor suppressor genes are two types of genes that ordinarily keep the cell cycle functioning as it should. explain the roles of these two types of genes, and explain what can occur when these types of gene are not working properly. provide at least two different examples of cancers associated with mutations of these types of genes..

The purpose of the proto-oncogenes under normal circumstances is to make sure that cells proliferate, in other words the oncogenes stimulate cell production. But when a normal, healthy ocogene cell becomes mutated or expresses at higher than normal levels it causes cancer. The first oncogenic virus was discovered in 1916 and called the Rous virus after the person who discovered it, Peyton Rous. Rous viruses represent a family of viruses called the retro viruses. Retro viruses contain a genetic material called ribonucleic acid (RNA).

The realists were right about the war in Ukraine Lily Lynch Far from the flashy, hope filled “David vs Goliath” narratives of resistance and reclamation of its first months, the Ukraine-Russia war has slowed to a drivel – and alongside it domestic morale, foreign support and US funding. Initially ignored warnings of Ukrainian “false hope” were not so incorrect, Lynch suggests, as she questions what version (if any) of Ukraine’s future is actually attainable.

Who is afraid of Martin Heidegger? Lyndsey Stonebridge In the rootless world of the 1920s, Heidegger’s ideas about Being (with a capital B, signifying the full meaning of human existence) ripped up the ground of philosophy. The truth exists only in our Being. “Being-there” – “ Dasein ”, in Heidegger’s distinctive terminology – is what matters; there in history, gliding on nothingness, with no other certain knowledge than that of our own death. There is no plot to follow, save the “hidden primordiality” of Being itself. This essay looks at why the most radioactive philosopher of the 20th century still speaks to us.

Gramsci in Florida Alberto Toscano While talk of a “Gramscian vanguard” is largely a conspiratorial fabrication of the right, it could also serve as a spur for a somewhat rudderless left to reflect on what hegemony might look like today, on what it would take to become the threat to capitalism, patriarchy and white nationalism that the right already takes it to be.

Arno J Mayer’s 20th Century Enzo Traverso The American historian Arno J Mayer belongs to an extraordinary generation of German-speaking Jewish scholars – George L Mosse, Raul Hilberg, Peter Gay and Fritz Stern among others – who were born in Europe between the end of the First World War and Hitler’s rise to power, reaching their maturity during the Second World War. The cataclysms of the 20th century forged their mental  habitus  and gave them a sharp sense of  history . Mayer helped transform the writing of history – and with it our understanding of the modern world.

The Only Thing More Dangerous Than Authoritarianism

The forces of Christian nationalism are now ascendant both inside the Church and inside the Republican Party.

A black-and-white photo of a Christmas tree outside in the snow

This Christmas season, I have been reflecting on the words of my favorite author, C. S. Lewis, who once observed: “I have learned now that while those who speak about one’s miseries usually hurt, those who keep silence hurt more.”

Speaking about American evangelicalism was never my intention. Having grown up steeped in Christianity’s right-wing subculture—the son of a megachurch minister, a follower of Jesus, someone who self-identified as “evangelical” since childhood—I was a reliable defender of the faith. I rejected the caricatures of people like my parents. I took offense at efforts to mock and marginalize evangelicals. I tried to see the best in the Church, even when the Church was at its worst.

It took the loss of my father, and the traumatic events surrounding his funeral—as I write in the prologue of my new book, The Kingdom, The Power, and the Glory , which is excerpted in our latest issue —to reconsider the implications of that silence.

The corruption of American Christianity is nothing new: Modern-day pharisees from Jerry Falwell Sr. to Paula White have spent 50 years weaponizing the Gospel to win elections and dominate the country, exploiting the cultural insecurities of their unwitting brethren for political, professional, and financial gain, all while reducing the Gospel of Jesus Christ to a caricature in the eyes of unbelievers. The resulting collapse of the Church’s reputation in this country—with Sunday attendance, positive perceptions of organized religion, and the number of self-identified Christians all at historic lows—leaves evangelicals estranged from their secular neighbors like never before. Unbelievers might well prefer it this way. They might be tempted to shrug and move along, assuming that the crack-up of evangelicalism isn’t their problem. They are mistaken.

The crisis at hand is not simply that Christ’s message has been corroded, but that his Church has been radicalized. The state-ordered closings of sanctuaries during COVID-19, the conspiracy-fueled objections to Joe Biden’s victory in 2020, the misinformation around vaccines and educational curricula—these and other culture-war flash points have accelerated notions of imminent Armageddon inside American Christendom. A community that has always felt misunderstood now feels marginalized, ostracized, even persecuted. This feeling is not relegated to the fringes of evangelicalism. In fact, this fear—that Christianity is in the crosshairs of the government, that an evil plot to topple America’s Judeo-Christian heritage hinges on silencing believers and subjugating the Church—now animates the religious right in ways that threaten the very foundations of our democracy.

“You sound like a hysterical maniac if you say the government’s coming after us. But I believe they are,” Robert Jeffress, the Dallas pastor and longtime Trump loyalist, told me in the book. “It happened in Nazi Germany. They didn’t put six million Jews in the crematorium immediately … It was a slow process of marginalization, isolation, and then the ‘final solution.’ I think you’re seeing that happen in America. I believe there’s evidence that the Biden administration has weaponized the Internal Revenue Service to come after churches.” (The “evidence” Jeffress cited in making this leap—bureaucratic regulations clearing the way for concentration camps—was nonexistent. When pushed, he mentioned a single court case that was ultimately decided in favor of religious liberty.)

Mobilizing in response to this perceived threat, the forces of Christian nationalism—those who seek to demolish the wall between Church and state, asserting far-right religious dominion over the government as well as the country’s core institutions—are now ascendant both inside the Church and inside the Republican Party. It is no coincidence that, just recently, Donald Trump began suggesting that he would ban any migrant from entering the United States unless they are Christian. Those who don’t share “our religion,” the famously impious ex-president pronounced, won’t be welcome here if he’s elected again. Many of the people poised to hold high-ranking posts in a second Trump administration don’t view today’s societal disputes through the lens of Republican versus Democrat or of conservative versus progressive, but rather of good versus evil.

Perhaps the only thing more dangerous than authoritarianism is authoritarianism infused with religious justification. It hardly matters whether the would-be tyrant is personally devout; Vladimir Putin’s lack of theology didn’t stop him from partnering with the Russian Orthodox Church to frame the bloody invasion of Ukraine as God’s ordained conquest of a satanic stronghold. To believe that it couldn’t happen here—mass conflict rooted in identitarian conviction and driven by religious zeal—is to ignore both 20th-century precedent and the escalating holy-war rhetoric inside the evangelical Church.

I am a follower of Jesus Christ. I believe that God took on flesh in order to model servanthood and self-sacrifice; I believe he commanded us to love our neighbor, to turn the other cheek toward those who wish us harm, to show grace toward outsiders and let our light shine so they might glorify our heavenly Father. Not all professing Christians bother adhering to these biblical precepts, but many millions of American believers still do. It is incumbent upon them to stand up to this extremism in the Church.

Yet the responsibility is not theirs alone. No matter your personal belief system, the reality is, we have no viable path forward as a pluralistic society— none —without confronting the deterioration of the evangelical movement and repairing the relationship between Christians and the broader culture. This Christmas, I pray it might be so.

In 1969, the federal government announced that it would hand out millions of dollars in subsidies to companies willing to try something new: build houses in factories.

Then as now, America was in the throes of a housing crisis. There weren’t enough places to live. Mass production provided Americans with abundant and cheap food, clothing, cars and other staples of material life. But houses were still hammered together by hand, on site. The federal initiative, Operation Breakthrough , aimed to drive up the production of housing — and to drive down the cost — by dragging the building industry into the 20th century.

It didn’t work. Big companies, including Alcoa and General Electric, designed new kinds of houses, and roughly 25,000 rolled out of factories over the following decade. But none of the new home builders long survived the end of federal subsidies in the mid-1970s.

Last year, only 2 percent of new single-family homes in the United States were built in factories. Two decades into the 21st century, nearly all U.S. homes are still built the old-fashioned way: one at a time, by hand. Completing a house took an average of 8.3 months in 2022, a month longer than it took to build a house of the same size back in 1971.

Federal housing policy in the decades since the failure of Operation Breakthrough has focused myopically on providing financial aid to renters and homeowners. The government needs to return its attention to the supply side. Opening land for development, for example by easing zoning restrictions, is part of the answer, but reducing building costs could be even more constructive. Land accounts for roughly 20 percent of the price of a new house ; building costs account for 60 percent. (The price of land is a larger factor in coastal cities like New York, but a vast majority of new housing in the United States is built on cheap land outside cities.)

The tantalizing potential of factory-built housing, also known as modular housing, continues to attract investors and entrepreneurs, including a start-up called Fading West that opened a factory in 2021 in the Colorado mountain town of Buena Vista. But Fading West, and similar start-ups in other parts of the country, need government help to drive a significant shift from handmade housing to factories. This time, there is reason to think it could work.

On a windy morning last month, I watched as wooden platforms the size of train cars moved down the Fading West assembly line, advancing to a new station every few hours as workers added walls and windows, wiring and insulation, dishwashers and cabinets. The finished boxes are trucked to building sites and swung into place by cranes. Houses consist of two to four boxes. Once they’re knitted together, the result looks like a traditional home.

Charlie Chupp, the chief executive, previously ran a company that built and shipped all the pieces of new stores for Starbucks, Einstein Bros. Bagels and other restaurant chains. Fading West is seeking to apply a similar model to building homes and apartments. “We see ourselves as being in manufacturing, not construction,” says Eric Schaefer, a former pastor who is now the company’s chief evangelist, bending the ear of politicians, reporters and developers about the potential benefits of mass production — and the changes necessary to support it.

Final assembly happens so quickly that it almost seems like a magic trick. In Poncha Springs, a town 30 minutes south of Buena Vista, I watched as a crane swung a 19,894-pound box over a concrete foundation. A worker on each corner checked the fit while two more waited in the basement to connect it to the foundation. As it was secured, a truck arrived with the next box.

The team of eight workers has sometimes assembled four houses in a single day.

Joanna Schwartz, the chief executive of Quartz Properties, which is using Fading West’s boxes to build the homes, said buyers sometimes come to see the show. “They didn’t have a house in the morning and then in the afternoon they can walk through it,” she said.

Fading West says houses from its factory can be completed in as little as half the time and at as little as 80 percent of the cost of equivalent handmade homes, in part because the site can be prepared while the structure is built in the factory. A 2017 analysis by the Terner Center for Housing Innovation at the University of California, Berkeley, found similar savings for the construction of three- to five-story apartment buildings using modular components.

Factory building has other advantages, too. It can reduce waste, maintain higher standards of consistency and produce homes that are more energy efficient. It is not subject to rain delays.

It also offers a solution to the home-building industry’s growing problems finding enough qualified workers, especially in high-cost areas. Manufacturers like Fading West can build where labor is cheaper and then ship homes to the places where people want to live.

But there are good reasons modular housing has remained the next big thing for a long time.

One basic problem is that houses are large objects, and unlike cars or airplanes, they are not designed to move. The result is that the savings from factory production are partly offset by the cost of transportation. (Some companies reduce transportation costs by shipping homes in smaller pieces, an approach pioneered by Sears and other retailers of “build your own home” kits in the early 20th century, but that just shifts the cost from transportation to assembly.)

The volatility of the housing market is also a problem. Traditional home builders rely on contract workers who are easily dismissed during downturns. Factory builders, which have high fixed costs, tend to go bankrupt. Housing downturns have ended a long line of ambitious and well-funded efforts to create the Model T of the housing industry. In 2006, on the cusp of the most recent housing crash, factory builders produced more than 70,000 homes . Since the crisis and the resulting wipeout, annual production has not exceeded 30,000 houses.

Neither volatility nor transportation costs might matter if factory home builders could match the efficiency gains found in other kinds of mass production. Brian Potter, a senior infrastructure fellow at the Institute for Progress, a nonpartisan think tank focused on technological innovation, gives the example of the Ford Taurus. Experimental models of the 1996 Taurus were built by hand, which cost almost half a million dollars per car. The car eventually retailed for less than $20,000.

Factory home builders have struggled to streamline construction. Mr. Potter spent several years looking for ways to make housing construction more efficient, an effort he narrated on a fascinating blog , before concluding that significant progress wasn’t likely. “Almost any idea that you can think of for a way to build a single-family home cheaper has basically been tried, and there was probably a company that went bankrupt trying to do it,” Mr. Potter told me.

I think the history of the auto industry provides reason for more optimism. One lesson is that progress requires production at scale. There are a handful of car companies that each make millions of cars, and hundreds of home builders building a few hundred homes a year. Fading West, which aims to produce as many as 1,000 homes a year, says that isn’t enough to justify investments in automation.

Efficiency gains also come from doing the same thing over and over again, but the idiosyncrasies of local building codes make that impossible. In Colorado alone, by Mr. Schaefer’s count, there are more than 300 distinct building codes, requiring adjustments for each new batch of homes. Fading West found that it had to use different roof designs for homes headed to the city of Fairplay and to a development just outside the city, because the county has stricter snow load regulations.

A sequel to Operation Breakthrough could help the industry overcome those challenges. The Canadian government’s Rapid Housing Initiative is providing support for large-scale modular manufacturing by setting tight construction deadlines for affordable housing projects that obtain government funding, an approach the United States could emulate on an even larger scale.

The government also can push for the standardization of building materials and building regulations. Herbert Hoover, the great champion of industrial standardization, who during his years as commerce secretary in the 1920s worked successfully to establish uniform rules for products such as paving bricks, milk bottles and blackboards, argued that establishing consistent standards was the nearest thing to a free lunch. It would increase productivity, benefiting companies, workers and customers. Florida and California will always have somewhat different building codes, because hurricanes and earthquakes pose different challenges. But there is no reason for Colorado to have 300 different codes.

If it seems far-fetched that the government could revolutionize the home-building business, take a look at what sits on top of a growing number of American homes. The government has driven the spread — and driven down the cost — of solar panels through decades of investment and subsidies.

It’s time to pay similar attention to the buildings underneath.
