the condition of a dynamic genetic system in which the several rates of change between all possible pairs of parts are such that the composition is invariant.

genetic equilibrium

the state within a population at which the frequency of alleles and genotypes does not change from generation to generation. It routinely occurs in large, interbreeding populations in which mating is random and there are no or relatively few mutations. See also Hardy-Weinberg equilibrium principle.

genetic equilibrium

or

equilibrium of population

a state that occurs when GENE FREQUENCIES are constant in a population for several generations. Such equilibrium may also be found where SELECTION is operating to produce a stable GENETIC POLYMORPHISM. See also HARDY-WEINBERG LAW.
