B) Geographic barrier, genetic divergence, reproductive isolation
C) Genetic divergence, geographic barrier, reproductive isolation
D) Genetic divergence, reproductive isolation, geographic barrier
E) Reproductive isolation, genetic divergence, geographic barrier

Question

Quizplus · Accepted Answer

In allopatric speciation, a geographic barrier separates a population into two or more groups, leading to genetic divergence as each population experiences different selective pressures and mutations. Over time, this genetic divergence can lead to reproductive isolation between the populations, as their genetic differences prevent successful breeding even if they were to come into contact again. Therefore, the most likely sequence of events in allopatric speciation is (1) geographic barrier, (2) genetic divergence, and (3) reproductive isolation.
