Question

Quizplus · Accepted Answer

During sympatric speciation, reproductive isolation occurs between certain subpopulations even though they are living in the same geographic area. This can happen through various mechanisms such as changes in mating behavior, differences in ecology or niche specialization leading to different mating preferences, or polyploidy. Wide phenotype differences may or may not develop between subpopulations, and geographic separation is not a requirement for this type of speciation. Mutations may contribute to the differences between subpopulations, but they are not the sole cause.
