C)reduced hybrid fertility.
D)geographic isolation.

Question

Quizplus · Accepted Answer

Sympatric speciation occurs when a subset of a population becomes reproductively isolated within the same geographic area, often due to behavioral, ecological, or chromosomal changes. Allopatric speciation, on the other hand, requires a physical barrier to gene flow, such as a geographic barrier like a mountain range or a river. Reduced hybrid fertility is a mechanism by which hybrid offspring between two different species have reduced fertility and are unable to produce viable offspring. Geographic isolation is a component of allopatric speciation and refers specifically to the physical separation of populations by a geographic barrier.
