Introduction:
The Hardy-Weinberg principle describes the establishment of genotype frequencies in sexually-reproducing organisms. Genetic equilibrium will be achieved if the given conditions are followed:
1) No mutations occur in a population.
2) Population is closed to migration from other population.
3) Individuals in a population mate randomly with their genotypes.
4) All genotypes in a population survive and are able to reproduce.
