Allele Frequency from Genotype Counts

Enter genotype counts for AA, Aa, and aa. The app will calculate population size, allele frequencies, and the corresponding Hardy-Weinberg values.

p = (2AA + Aa) / 2N | q = (2aa + Aa) / 2N | N = AA + Aa + aa

p = frequency of the dominant allele (A) in the population | q = frequency of the recessive allele (a) | N = total number of individuals in the population.

Input

Enter genotype counts to begin.

This version uses genotype counts rather than phenotype counts, so the allele frequencies are calculated directly rather than estimated.

The Hardy-Weinberg values shown here are the frequencies expected from the calculated p and q.
