Hardy-Weinberg & SelectionLive
population genetics
Controls
Presets
Without selection, allele frequencies stay put and genotypes settle at p², 2pq, q² — Hardy-Weinberg equilibrium. Give the genotypes different fitness and selection shifts the allele frequency each generation. Heterozygote advantage (high Aa fitness) can hold both alleles in a stable balance.

Governing equation
Reading this result: Allele A is favored at every genotype, so directional selection drives p toward 1 and eventually fixes A.
