Allele Frequency Calculator

Calculate allele frequencies, genotype frequencies, and perform Hardy-Weinberg equilibrium analysis.

Population Name *

What would you like to calculate? *

Homozygous Dominant (AA) *

Number of AA individuals

Heterozygous (Aa) *

Number of Aa individuals

Homozygous Recessive (aa) *

Number of aa individuals

Allele Frequency (p or q) *

Frequency of allele A (p) or a (q)

Allele Type *

🧬 Allele Frequency Formulas:
p: (2AA + Aa) / (2N) • q: (2aa + Aa) / (2N) • Hardy-Weinberg: p² + 2pq + q² = 1
