Definitions for "Hardy-Weinberg equilibrium"
A condition under which the genotypic frequencies in a diploid population are equal to the products of the allele frequencies involved.
The steady-state relationship between relative frequencies of two or more alleles in an idealized population; both the allele frequencies and the genotype frequencies will remain constant from generation to generation in a population breeding at random in the absence of evolutionary forces. Hardy-Weinberg theorem An axiom maintaining that the sexual shuffling of genes alone cannot alter the overall genetic makeup of a population. haustorium pl. haustoria In parasitic fungi, a nutrient-absorbing hyphal tip that penetrates the tissues of the host but remains outside the host cell membranes. Haversian system(ha- ver-shun) One of many structural units of vertebrate bone, consisting of concentric layers of mineralized bone matrix surrounding lacunae, which contain osteocytes, and a central canal, which contains blood vessels and nerves.
a mathematical model of genetic equilibrium: p2 + 2pq + q2 = 1.
