Question

frequency of allele is 0.6 and that of a allele is 0.4 what would be frequency of heterozygotes in random mating population?
plz give answer with elaborate

Answer 1

Allele frequency is the relative proportion of a particular allele among individuals of a population, According to Hardy-Weinberg equation, the frequency of dominant and recessive alleles in a population will remain constant from generation to generation if there is no mutation, selection, random drift and migration. As per Hardy-Weinberg equation                

p2+2pq+q2=1 p = dominant allele frequency                 q = recessive allele frequency                

p2=homozygous dominant genotype                 2pq = heterozygous genotype                

q2=homozygous recessive genotype                 In question p = 0.6 and q = 0.4                 Therefore, heterozygotes frequency is                

=2pq=2×0.6×0.4=0.48
