Question

Quizplus · Accepted Answer

Allopatric speciation requires a geographic barrier, such as a mountain range or a river, that separates a population and prevents gene flow, leading to the divergence of the two populations over time. In contrast, sympatric speciation occurs within a single geographic area without a physical barrier to gene flow, typically through mechanisms such as polyploidy or ecological specialization.
