Work out allele frequency instantly with clear inputs, formula shown and shareable results.
Counts alleles directly from genotype numbers: each homozygote contributes two copies and each heterozygote one.
Gene counting
p = (2 x homozygous dominant + heterozygous) / (2 x total individuals); q = 1 - p
No. Direct gene counting works whatever the mating structure, which is why it is preferred when genotypes are observable.
Then q must be estimated as the square root of the recessive phenotype frequency, which does assume equilibrium.
