The Hardy-Weinberg principle is fundamental to population genetics. This calculator helps you determine allele and genotype frequencies from any known value - whether it's the frequency of affected individuals, carriers, or either allele.
Hardy-Weinberg equilibrium describes how allele frequencies remain stable in a population when there's no evolution occurring. The equations p + q = 1 (for alleles) and p² + 2pq + q² = 1 (for genotypes) let us calculate all frequencies from just one known value.
Hardy-Weinberg Equations
p + q = 1, p² + 2pq + q² = 1Start from affected frequency, carrier rate, or allele frequency.
Get all allele and genotype frequencies from any single value.
Calculate expected numbers for any population size.
Calculate carrier frequencies for genetic disorders.
Learn and practice population genetics problems.
Estimate expected genotype distributions in populations.
Compare observed vs expected frequencies to detect selection.
HW equilibrium assumes: no mutation, random mating, no gene flow, infinite population size, and no selection. Real populations rarely meet all conditions, but it provides a useful baseline for comparison.
