Hardy-Weinberg’s law of genetic equilibrium :
G.H. Hardy (England) and W. Weinberg (Germany) made mathematical expression of the genetics and propound a Hardy – Weinberg’s law. According to it, the gene frequency of a randomly mating large population will remain constant from generation to generation in absence of mutations i.e. this community will remain in genetic equilibrium.
This law further state that the rate of evolution will be zero in the state of genetic equilibrium.
Five factors affect the Hardy-Weinberg’s law
- Gene flow
- Genetic drift
- Mutation
- Genetic recombination
- Natural selection
