Question

A population has two alleles for a given gene, d and
d. if the frequency of the dominant allele is 0.45 and the frequency of the recessive allele is 0.55, what will the frequency be for the recessive homozygous genotype

Answer 1

D = 0.45 is the dominant allele
d = 0.55 is recessive allele

D^2 + 2Dd + d^2 = 1

frequency of homozygous recessive genotype is d^2

(0.55)^2 = 0.3025
