A small number of animals moves away from a large ancestral population on the continental mainland and colonizes an island. Which of the following is likely to occur? A. Genetic diversity will decrease on the mainland, because of a population bottleneck. B. Alleles that were more rare on the mainland are likely to become more common on the island, because of the founder effect. C.
