Question

If the genotypic frequencies of AA, Aa, and aa are 0.6, 0.2, and 0.2, respectively, then the frequency of allele A is _____ and that of allele a is _____ . Group of answer choices

Answer 1

Answer:

The frequency of allele A = 0.7

The frequency of allele a = 0.3

Explanation:

Assume that p = frequency of allele A ad q = the frequency of allele a

According to Hardy Weinberg equilibrium

p + q = 1  

p² + 2pq + q² = 1
