In a Hardy-Weinberg population with two alleles A1 and A2 that are in equilibrium, the frequency of allele A2 is 0.1. What is the frequency of individuals with A1A1 genotype?
A) 0.20
B) 0.32
C) 0.42
D) 0.81

The frequency of allele A2 is 0.1, so the frequency of allele A1 is 1 - 0.1 = 0.9. The frequency of individuals with the A1A1 genotype is the square of the frequency of allele A1, which is 0.9^2 = 0.81.
