A basic concept in population genetics that relates the gene frequency to the genotype frequency. The Hardy-Weinberg law can be used, for example, to determine allele frequency and heterozygote frequency when the incidence of a genetic disorder is known.

Important principle of population genetics stating that, in a large, randomly mating population not affected by mutation, migration, or natural selection, allelic frequencies will not change and genot [..]

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.
