The Hardy-Weinberg theorem predicts that allele frequencies will remain constant in populations (evolution will not occur) when all of the following are true, except one. Select the exception.
A) The population must be large so that genetic drift is not occurring.
B) Migration into a population ensures new alleles are randomly distributed within a population.
C) All individuals within the population have an equal opportunity for reproduction.
D) No mutations are occurring or mutational equilibrium exists.
