Hardy-Weinberg Calculator

Calculate Hardy-Weinberg genotype frequencies from a dominant allele frequency, including the recessive allele frequency and all three genotypes

Frequently Asked Questions

What does the Hardy-Weinberg principle assume?

It assumes a large, randomly mating population with no mutation, migration, or natural selection. Under these idealized conditions, allele and genotype frequencies stay constant from one generation to the next.

How are the genotype frequencies calculated?

With dominant allele frequency p and recessive frequency q, the genotype frequencies come from expanding p plus q squared. This gives p squared for homozygous dominant, two p q for heterozygous, and q squared for homozygous recessive.
