The hardy-weinberg principle states that evolution will not occur in a population when environmental conditions are stable. when there is a change in allele frequencies in a gene pool of a population, evolution has happened. predict how two events—mutation and migration—will affect the hardy-weinberg principle.
any with this would be greatly appreciated!
