Question 7
You have sampled a population in which you know that the percentage of the homozygous recessive genotype (aa) is 36%.
Using that 36%, calculate the following- the frequency of the "a" allele. (q)
p2 + 2pq + q2 = 1 and p + q = 1
a
0.36
b
0.4
c
0.6
d
1
To calculate the frequency of the "a" allele (q), we can first determine the frequency of the aa genotype by taking the square root of the percentage provided:
Sqrt(0.36) = 0.6
Since the aa genotype represents the homozygous recessive genotype, the frequency of the "a" allele (q) would be the square root of the frequency of the aa genotype:
q = 0.6
Therefore, the correct answer is:
c) 0.6
