Which of the following does NOT tend to promote speciation?
A) the founder effect
B) gene flow
C) natural selection
D) polyploidy
E) disruptive selection

Question

Quizplus · Accepted Answer

Gene flow tends to homogenize populations and prevent speciation by bringing in new genetic variation from other populations. The other answer choices can all promote speciation in different ways. The founder effect can lead to isolation and limited gene flow, natural selection can drive divergence in traits, polyploidy can create new species by doubling the number of chromosomes, and disruptive selection can create divergent phenotypes within a population.
