Chapter 21, Problem 17P
Androgenetic alopecia (pattern baldness) is a complex trait in humans governed by several genes, but suppose a human population exists in which a single autosomal allele determines pattern baldness. This allele is dominant in males and recessive in females. The population is in Hardy-Weinberg equilibrium, and 51% of the men are bald.
| a. | What is the allele frequency of the baldness allele among males? |
| b. | What is the allele frequency of the baldness allele among females? |
| c. | What percentage of the women in this population will exhibit pattern baldness? |
| d. | Assuming random mating, what proportion of all matings should be between a bald man and a Page 742 nonbald woman? |
| e. | What percentage of the bald men in the population are heterozygotes? |
| f. | If a nonbald couple produces a bald son, what is the probability that their next son will be bald? |
| g. | A woman with androgenetic alopecia has a daughter, but nothing is known about the father. What is the probability that the daughter will be bald? |

- For each of the following characteristics, indicate whether it would be considered a discontinuous characteristic or a quantitative characteristic. Briefly justify your answer. a. Kernel color in a strain of wheat, in which two codominant alleles segregating at a single locus determine the color. Thus, there are three phenotypes present in this strain: white, light red, and medium red. b. Body weight in a family of Labrador retrievers. An autosomal recessive allele that causes dwarfism is present in this family. Two phenotypes are recognized: dwarf (less than 13 kg) and normal (greater than 23 kg). c. Presence or absence of leprosy. Susceptibility to leprosy is determined by multiple genes and numerous environmental factors. d.

- Suppose there is an autosomal locus of 2 alleles, A1 and A2, with probabilities (frequencies) p1 and p2, and the genotype probabilities (frequencies) are P(A1A1) = p1*p1, P(A1A2) = 2*p1*p2, and P(A2A2) = p2*p2, respectively. Prove the Hardy-Weinberg Law, i.e., after one generation of random mating, the genotype probabilities (frequencies) in the offspring are also P(A1A1) = p1*p1, P(A1A2) = 2*p1*p2, and P(A2A2) = p2*p2.
