Allopatric speciation occurs when
A) gene flow is maintained between two subgroups of a mother population.
B) two morphologically different subgroups of a species share the same habitat.
C) gene flow prevents genetic variants from being exchanged between subgroups.
D) a subgroup is physically isolated from the mother population and gene flow can no longer occur.

Question

Quizplus · Accepted Answer

Allopatric speciation occurs when a subgroup is physically isolated from the mother population and gene flow can no longer occur. This separation allows for genetic drift, mutations, and natural selection to act on the isolated subgroup, eventually resulting in the development of a new species.
