Explain the five conditions that need to be met for a population to be at genetic equilibrium according to Hardy and Weinberg (The Hardy-Weinberg principle).  Additionally, explain what conditions would have to have been met if the population evolved. Be detailed in your answer(s).

Definition Definition Principle that states that allele and genotype frequencies in any population will remain constant from one generation to another in the absence of other evolutionary forces. The Hardy-Weinberg principle is used for testing genotype frequency for population stratification and other non-random mating forms.
