ZoologyAt a particular locus, frequency of allele B is 0.8 and that of b is 0.2. What would be the frequency of heterozygotes in a random mating population in equilibrium?

At a particular locus, frequency of allele B is 0.8 and that of b is 0.2. What would be the frequency of heterozygotes in a random mating population in equilibrium?

A
0.64
B
0.48
C
0.32
D
0.16

Solution:

Frequency of dominant allele(B) p = 0.8

Frequency of recessive allele(b) q = 0.2

Frequency of heterozygotes is 2pq = 2 $\times$ 0.8 $\times$ 0.2 = 0.32
