Genetic equilibrium
From Wikipedia, the free encyclopedia
In theory, genetic equilibrium is a state in which a population is not evolving.
[edit] Assumptions For Genetic Equilibrium
- No gene mutations
- Large population size
- Isolated population (away from other populations of the same species)
- 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 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.
