Question

If the frequency of two alleles in a gene pool is 90%A and 10% a, what is the frequency of individuals in the population with the genotype Aa? Use the Hardy-Weinberg Equilibrium.

Answer 1

Answer: 0.18

Explanation:

From the question we know that p = 0.9 and q = 0.1. From this, We can compute the heterozygotes: 2pq = 2 (0.9) (0.1) = 0.18.
