Genetic Equilibrium

If all 5 Hardy-Weinberg assumptions are true, a population is said to be in genetic equilibrium. This means

• it is evolving

• it is not evolving

Select ALL of the following that violate the Hardy-Weinberg assumptions and would lead to a change in allele frequencies in a population.

• natural selection

• large population

• no mutations

• nonrandom mating

• no migration
