2pq
frequency of heterozygous genotype
2pq is a term used in genetics to calculate the frequency of heterozygous individuals in a population according to the Hardy-Weinberg equilibrium equation. The Hardy-Weinberg equilibrium equation is a mathematical formula that predicts the frequency of different alleles and genotypes in a population that is not evolving.
In this equation, p represents the frequency of one allele in the population, q represents the frequency of the second allele, and 2pq represents the frequency of heterozygous individuals who carry both alleles. This equation assumes that the population is large, has random mating, no mutations, no migration, no natural selection, and that the alleles are in a stable equilibrium.
Therefore, 2pq represents the frequency of heterozygous individuals who carry different alleles at a particular locus in a population under the assumptions of the Hardy-Weinberg equilibrium equation.
