16. According to the Hardy-Weinberg equation, the genotype frequencies for the three possible combinations of alleles in a population are described by the ratio p2 : 2pq : q2. a) Use this ratio to determine the genotype frequency in a population where p = 0.7 and q = 0.3. Show your reasoning. (3 points)
A1A1 =
A1A2 =
A2A2 =
b) Assume that A1 is a dominant allele that codes for purple leaves and A2 is a recessive allele that codes for white leaves. What will be the frequencies of purple and white phenotypes in this population? (1 point)
