Question

(p + q)² = p² + 2pq = q² = 1 represent ______.

Options

• molecular genetics

• mendelian genetics

• population genetics

• biometrics

Answer 1

(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.
