The correct answer is option C
The frequency of the homozygous recessive genotype
In the Hardy-Weinberg equation, p is the frequency of the dominant allele, and q is the frequency of recessive allele then the frequency of genotype is represented by
p^2 = p x p = frequency of the homozygous dominant genotype ( AA)
q^2 = q x q = frequency of the homozygous dominant genotype (aa)
2 pq = p x q = The frequency of the heterozygous dominant genotype ( Aa)
