The law that states that the frequencies of genotypes in a population at a locus are determined by random mating and allele frequency.

A mathematical statement of the concept that gene and genotype frequencies are constant from generation to generation in a large, interbreeding population with random mating in the absence of selection, mutation, or migration.

In an infinitely large population, gene and genotype frequencies remain stable as long as there is no selection, mutation, or migration. In a panmictic population in infinite size, the genotype frequencies will remain constant in this population. For a biallelic locus where the allele frequencies are p and q: p2 + 2pq + q2 = 1 (see Notes on Population Genetics for more). head -- That part of the body at the "front" end, where the brain, mouth, and most sensory organs are located.

A rule which relates the frequencies of genotypes at a locus in a population to the frequencies of the alleles at that locus.

the concept that both gene frequencies and genotype frequencies will remain constant from generation to generation in an infinitely large, interbreeding population in which mating is at random and there is no selection, migration, or mutation

The mathematical expression of the equilibrium of allelic genetic markers within the population. A mathematical model that allows for the prediction of occurrence of genetic markers in a population and states that in a large random intra-breeding population, not subjective to excessive selection or mutation, the gene and genotype frequency will remain constant over time.(p + q)2 = P2 + 2 pq + q2 = 1 p and q represent the frequency of two allelic genes in a two allele system. p2 and q2 represent the frequencies of homozygotes. 2pq represents the frequency of heterozygotes. In a multiple allelic system: (p + q + r + s)2 = 1 r and s represent additional alleles in a multiple allele system.
