Question

question
when two populations are reproductively isolated, what else must occur for speciation to happen?
select an answer
a. gene flow
b. genetic divergence
c. coevolution
d. convergent evolution

Explanation:

Speciation occurs when two populations that are reproductively isolated also experience genetic divergence. Gene flow would prevent speciation by mixing genes. Co - evolution is about the reciprocal evolution of different species. Convergent evolution is when different species independently evolve similar traits. Genetic divergence leads to differences in genetic makeup over time, which can result in new species.

Answer:

B. genetic divergence
