Two species regularly come into contact and form hybrids that have higher fitness than either of the parental species. What are the possible consequences of regular hybridization between these species? Check all that apply.

Question

Quizplus · Accepted Answer

The formation of hybrids with higher fitness can lead to the evolution of a third species (A), the extinction of the parental species if hybrids outcompete them (C), and increased gene flow between the parental species as hybrids may backcross with them (D). Reinforcement of prezygotic isolating mechanisms (B) is unlikely because hybrids have higher fitness, reducing the selective pressure for such mechanisms.
