Question

What is the frequency of allele g?

A. 0.42
B. 0.58
C. 0.70
D. 0.91

Answer 1

1. Option C
2. Option A
1. The frequency of the recessive alleles q = 1 -0.5 = 0.5 = 50%
2. The frequency of dominant alleles = 1 - 0.3 = 0.7
To calculate for the number of heterozygous use 2pq = 2 x 0.7 x 0.3 = 0.42
