In large populations,the Hardy-Weinberg equilibrium principle can be used to determine whether evolution is occurring.For instances where allelic frequencies are indicated by p and q,the resultant genotype frequencies are indicated by which of the following equations?
A) p² + q²
B) p² + pq + q²
C) p² + 2pq + q²
D) p2 + (pq)² + q²

Question

Quizplus · Accepted Answer

The correct equation for genotype frequencies in the Hardy-Weinberg equilibrium principle is p² + 2pq + q². This equation accounts for the three possible genotype combinations: homozygous dominant (p²), homozygous recessive (q²), and heterozygous (2pq). Option A (p² + q²) only accounts for homozygous genotypes and option B (p² + pq + q²) does not distinguish between heterozygotes and homozygous recessive genotypes. Option D (p² + (pq)² + q²) is not a correct equation for the genotype frequencies in the Hardy-Weinberg equilibrium principle.
