A gene locus has two alleles A, a. If the frequency of dominant allele A is 0.4, then what will be the frequency of homozygous dominant, heterozygous and homozygous recessive individuals in the population?

p=0.4p+q=1q=1-0.4=0.6Frequency of homozygous dominant individuals (AA) =p2=0.4×0.4=0.16Frequency of heterozygous dominant individuals (Aa) =2pq=2×0.4×0.6=0.48Frequency of homozygous recessive individuals (aa) =q2=0.6×0.6=0.36
