genetic equilibrium

It has been suggested that this article or section be merged into Hardy-Weinberg principle. (Discuss)

In theory, genetic equilibrium is a state in which a population is not evolving.

Assumptions For Genetic Equilibrium

• No gene mutations
• Large population size
• Limited-to-no immigration or emagration
• Gene of interest has no effect on survival or reproduction
• Mating is random

Rarely, if ever, do all five conditions prevail at the same time in nature. Gene mutation is infrequent but inevitable. Three processes may drive a population away from genetic equilibrium--natural selection, gene flow, and genetic drift.

Deer, alligators and mice have high amounts of genetic equilibrium.

When a population has reached genetic equilibrium, that means that the species will stop evolving and will stay in its present form.

Genetic Equilibrium: When a Gene pool is no longer creating new genes to keep the certain species from evolving anymore than they already have. Compare to: Hardy-Weinberg equilibrium
