In population genetics, the genotype frequency is the frequency or proportion (i.e. 0 < f < 1) of genotypes in a population.

It may be denoted thus:

$f(\mathbf{AA})$

Compare allele frequency.

The Hardy-Weinberg law predicts genotype frequencies from allele frequencies under certain conditions, in which case:

$f(\mathbf{AA}) = p^2$

$f(\mathbf{Aa}) = 2pq$

$f(\mathbf{aa}) = q^2$

Genotype frequencies may be represented by a De Finetti diagram.
