Har·dy-Wein·berg e·qui·lib·ri·um

(har'dē wīn'bĕrg),
that state in which the genetic structure of the population conforms to the prediction of the Hardy-Weinberg law; it is not a stable equilibrium, although for a large mating population it may be approximated.


Godfrey H., English mathematician, 1877-1947.
Hardy-Weinberg equilibrium - the state in which the genetic structure of the population conforms to the prediction of the Hardy-Weinberg law. Synonym(s): random mating equilibrium
Hardy-Weinberg law - if mating occurs at random with respect to any one autosomal locus in a population in which the gene frequencies are equal in the two sexes, and the factors tending to change gene frequencies are absent or negligible, then in one generation the probabilities of all possible genotypes will on average equal the same proportions as if the genes were assembled at random.
