Genetic Balance

Genetic equilibrium is a situation in which the distribution of alleles in a population remains constant from generation to generation (in the absence of selection or mutation).

Genetic equilibrium is achieved when allele frequencies in a population do not change over time. This occurs when evolutionary forces such as natural selection, mutation, genetic drift and migration balance each other.

For example, if allele A occurs with a frequency of 60%, and allele a - with a frequency of 40%, and these frequencies are maintained from generation to generation, then genetic equilibrium has been established in the population at this locus.

Genetic equilibrium is an important concept in population genetics. It allows you to predict how the frequencies of alleles and genotypes in a population will change over time. Disequilibrium leads to evolutionary changes in the population.
