Detailed explanation-1: -Hardy Weinberg equation says, p2+2pq+q2=1, where q2 is the frequency of homozygous recessive gene.
Detailed explanation-2: -Hence, the term q2 refers to the frequency of the homozygous recessive genotype in a given population and not a particular locus.
Detailed explanation-3: -The frequency of genotypes in a population can be represented by p2+2pq+q2= 1, with p2 equal to the frequency of the homozygous dominant genotype, 2pq equal to the frequency of the heterozygous genotype, and q2 equal to the frequency of the recessive genotype.
Detailed explanation-4: -The Hardy-Weinberg Equation q = the frequency of the recessive allele in a population. 2 p q 2pq 2pq = the frequency of the heterozygous dominant genotype. p2 = the frequency of homozygous dominant genotype. q2 = the frequency of homozygous recessive genotype.
Detailed explanation-5: -So, the correct answer is ‘2pq’
