Question

Quizplus · Accepted Answer

Reinforcement is the process where prezygotic barriers to reproduction evolve to strengthen or maintain reproductive isolation between populations that are already partially reproductively isolated due to postzygotic barriers. This helps to avoid the production of unfit hybrids and further solidifies the distinction between the species.
