State

Allele frequency is the proportion of all copies of a gene in a population's gene pool that one specific allele accounts for.

Show

Counting a specific allele's copies and dividing by the total gene copies across the whole population gives its frequency.

Watch for

Allele frequency describes the whole gene pool, per Bio 1689 — not the fraction of individuals who are heterozygous or homozygous.
