In a population at Hardy–Weinberg equilibrium, allele frequencies
A.remain constant across generations
B.always drift randomly
C.increase for dominant alleles
D.halve every generation
Explanation
Core Concept
Hardy–Weinberg equilibrium predicts genotype frequencies under assumptions that include random mating. Nonrandom mating can change genotype frequencies even without changing allele frequencies by itself. Allele frequencies remain constant only when evolutionary forces such as selection, drift, mutation, and gene flow are absent or negligible.
Correct Answer
Aremain constant across generations
