PCB 3063-Sec 799 Homework 11 2 3 1 23 Question 7: (3 points) The ability to taste the bitter chemical phenylthiocarbamide is determined by a single pair of alleles, of which T for taster is dominant to r for nontaster. A study of a Caucasian population revealed 70% were tasters. Assume the population satisfies the conditions of Hardy-Weinberg equilibrium. a. Calculate the frequencies of the alleles 7 and 1, and the frequencies of the genotypes TT, Tt, and it. b. Determine the probability of a nontaster child from a faster taster mating. Question 8: (2 points) A population in Hardy-Weinberg equilibrium has eight times as many heterozygotes as homozygous recessives. What is the frequency of the dominant allele? Question 9: (4 points)
