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 p^2: 2pq: q^2.
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)
