Allopatric Speciation Can Involve

Question

Allopatric speciation can involve
A) recolonization without reproductive isolation.
B) gene flow.
C) genetic drift.
D) sharing a habitat.

Accepted Answer

Allopatric speciation involves geographical separation of populations, which can lead to genetic drift and ultimately the accumulation of genetic differences that prevent interbreeding. Recolonization without reproductive isolation (A) and sharing a habitat (D) would not lead to allopatric speciation. Gene flow (B) would also hinder the accumulation of genetic differences and can actually prevent speciation from occurring.
