When the allele frequencies in a population stop changing, the population is at genetic equilibrium. In order to solve this problem, Godfrey Hardy and Wilhelm Weinberg developed the Hardy-Weinberg principle. 2pq signifies the frequency of Aa, or the heterzygote. 1 is the sum of all of the individuals in the specific population. Through this equation, a population can be examined as being at genetic equilibrium or not.
Genetic equilibrium signifies a stop in the evolutionary process, or stasis.
However, the principle only holds true when the species reproduces through sexual reproduction. Genetic equilibrium is always true if five specific conditions are met. First off the population size must be considerably large. No mutations can be occurring in the population. Environmental factors mustn t be causing natural selection to occur.
