Match the appropriate evolutionary force with the effects on allele frequencies over time in a population. Mutation acting alone as a force will cause changes in allele frequencies very quickly. Migration leads to homogenization between populations with increased gene flow. Genetic drift only causes allele frequency changes in very small populations. Selection is the result of bottleneck events.

Migration of random individuals will eventually homogenize allele frequencies across populations unless it is countered by another mechanism of evolution. Which of the following evolutionary forces is most likely to maintain the unique allele frequency of a non-mating-related gene in a population under the influence of gene flow? Natural selection Genetic drift Mutation Sexual selection Hardy-Weinberg equilibrium
Which evolutionary force occurs when fertile individuals migrate between populations having different allele frequencies? Group of answer choices genetic drift gene flow mutation natural selection
