B) adaptation
C) directional selection
D) gene flow

Question

Quizplus · Accepted Answer

Gene flow refers to the exchange of alleles between populations of the same species. Geographic isolation limits or completely prevents gene flow between populations, which can result in genetic differences and reduced adaptation. Directional selection can still occur in geographically isolated populations as long as there is genetic variation present, but it may not have the same impact as it would in a larger gene pool.
