Allele frequency, or gene frequency, is the relative frequency of an allele (variant of a gene) at a particular locus in a population, expressed as a fraction or percentage.

WebDetermining the allele frequency The first Hardy-Weinberg equation ( p + q = 1) concerns estimating the frequency of alleles in a population. Each gene usually has two alleles (diploid organism), one from each parent. These alleles are denoted as the dominant ( A) and recessive ( a) forms.
