The Hardy-Weinberg equilibrium is a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors. The principle predicts that both genotype and allele frequencies will remain constant. The Hardy-Weinberg principle describes an idealized state of a population. For a population to be in this kind of state, there cannot be any gene mutations, migrations of individuals, genetic drift and natural selection. Also, random mating must occur. When all these conditions are met, it is said that the population is in equilibrium. But because all of these things commonly occur in nature, the Hardy-Weinberg equilibrium rarely applies in reality. However, The Hardy-Weinberg equations can still be used for any population, even if it is not in equilibrium. There are two equations:
