In the Hardy–Weinberg model, which population-size condition helps keep allele frequencies stable from one generation to the next?

A.The population is large enough that genetic drift is negligible
B.as small as possible
C.asexual
D.haploid

Explanation

Core Concept

Hardy–Weinberg equilibrium assumes a sufficiently large population that random sampling effects are negligible, along with random mating and the absence of evolutionary forces such as selection, migration, and mutation. An infinitely large population is a mathematical idealization, not the wording AP students should be required to choose.

Correct Answer

AThe population is large enough that genetic drift is negligible
