Question

KollegeApply · Accepted Answer

(p + q)2 = p2 + 2pq = q2 = 1 represent population genetics. Explanation: This equation describes the expected frequencies of genotypes in a population under certain assumptions such as random mating, no selection, no mutation, no migration, and large population size. Here (p) and (q) represent the frequencies of two alleles at a locus, and the equation predicts the genotype frequencies (p2) (homozygous dominant), (2pq) (heterozygous), and (q2) (homozygous recessive) summing to 1.
