The allele frequency represents the incidence of a gene variant in a population. Alleles are variant forms of a gene that are located at the same position, or genetic locus, on a chromosome.

The Hardy-Weinberg equation is a mathematical equation that can be used to calculate the genetic ... p 2 + 2pq + q 2 = 1 where p is the frequency of the "A" allele and q is the frequency of ...
