Suppose we find a population with 60 AA individuals, 20 Aa individuals, and 20 aa individuals, what is the allele frequency of A?
A) 0.20
B) 0.40
C) 0.60
D) 0.70

Question

Quizplus · Accepted Answer

The allele frequency of A can be calculated by taking the total number of A alleles and dividing it by the total number of alleles. Here, there are 60 AA individuals (2 A alleles each), 20 Aa individuals (1 A allele each), and 20 aa individuals (0 A alleles). So, the total number of A alleles is (60*2) + (20*1) = 120 + 20 = 140. The total number of alleles is 2*(60+20+20) = 200. Therefore, the frequency of A is 140/200 = 0.70.
