Hardy-Weinberg Genotype Estimates from Phenotype Counts

Enter the counts for the dominant and recessive phenotypes. Assuming Hardy-Weinberg equilibrium, the app will estimate allele frequencies and the expected genotype counts and frequencies.

q² = recessive / N | q = √q² | p = 1 − q | AA = p², Aa = 2pq, aa = q²

N = total number of individuals | p = frequency of allele A | q = frequency of allele a | aa is inferred from the recessive phenotype.

Input

Dominant phenotype count

Recessive phenotype count

Enter phenotype counts to begin.

This estimator assumes Hardy-Weinberg equilibrium. Because the dominant phenotype combines both AA and Aa, those genotypes are estimated rather than observed directly.

These results are estimates under Hardy-Weinberg equilibrium. The recessive phenotype is used to infer q², then q, p, and the expected genotype distribution.
