The heritability for egg weight in a group of chickens on a farm inMaine is 0.95. Are the following statements regarding this heritabilitytrue or false? If a statement is false, explain why.A. The environment in Maine has very little effect on the outcomeof this trait.B. Nearly all of the phenotypic variance for this trait in this groupof chickens is due to genetic variance.C. The trait is polygenic and likely to involve a large number ofgenes.D. Based on the observation of the heritability in the Mainechickens, it is reasonable to conclude that the heritability foregg weight in a group of chickens on a farm in Montana isalso very high.

In domestic chicken, feather colour and shape are two traits which are controlled by autosomal alleles that are co-dominant. Table 2 shows the alleles and phenotype of both traits. The heterozygous state for feather colour is grey while the heterozygous state for feather shape is mildly frizzled. TABLE 2 Trait Feather colour Allele CB CW SS SF Effect Produces black feathers in homozygotes Produces white feathers in homozygotes Produces straight feathers in homozygotes Produces frizzled feathers in homozygotes Feather shape A farmer bred a black frizzled rooster with a grey mildly frizzled hen. Draw a genetic diagram to show the expected results of this cross. Include in your answer the phenotypic ratios. Is it necessary to do a test cross to determine the genotypes of the offspring? Explain your answer. The farmer would like all his chickens grey and mildly frizzled. What would you advise him to do? Explain your answer.

A danger in computing heritability values from studiesinvolving genetically related individuals is the possibility that theseindividuals share more similar environments than do unrelatedindividuals.

A genetics researcher determines that the broad-sense heritability of height among Southwestern University undergraduate students is 0.90. Which of the following conclusions would be reasonable? Explain your answer. a. Sally is a Southwestern University undergraduate student, so 10% of her height is determined by nongenetic factors. b. Ninety percent of variation in height among all undergraduate students in the United States is due to genetic differences. c. Ninety percent of the height of Southwestern University undergraduate students is determined by genes. d. Ten percent of the variation in height among Southwestern University undergraduate students is determined by variation in nongenetic factors. e. Because the heritability of height among Southwestern University students is so high, any change in the students’ environment will have minimal effect on their height.

Population A consists of 100 hens that are fully isogenicand that are reared in a uniform environment. Theaverage weight of the eggs they lay is 52 g, and the variance is 3.5 g2.

Height in humans is controlled by the additive action of genes and the action of environmental factors. For the purposes of this problem, assume that height is controlled by four genesA, B, C, and Dand that there are no environmental effects. Assume further that additive alleles contribute two units of height and partially additive alleles contribute one unit of height. a. Given these assumptions, can two individuals of moderate height produce offspring that are much taller and shorter than either parent? If so, how can this happen? b. Can someone of minimum height and someone of intermediate height have children taller than the parent of intermediate height? Why or why not?
