Definitions for "Hardy-Weinberg law"
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.
