The Hardy-Weinberg principle names 5 conditions that prevent evolution. Using those same 5 variables, describe a population that would be evolving. The Hardy-Weinberg principle states that when allele frequencies remain constant, a population is in genetic equilibrium (not evolving). There are 5 conditions that maintain those constant frequencies.
*the population is very large
*there is no immigration or emigration
*mating is random
*there are no mutations
*there is no natural selection (no reproductive advantage)
