How do you expect the genetic diversity of the island turtles to compare to genetic diversity of the mainland turtle population they originated from? Group of answer choices A. Genetic diversity should be similar, since they are the same species. B. Genetic diversity should be higher for the island turtles, because the new environment will produce new alleles. C.
