Question

Quizplus · Accepted Answer

Hybrid zones can result from secondary contact between previously isolated populations that have diverged and evolved unique traits. Such hybrids may be less fit than their parental species due to genetic incompatibilities or reduced hybrid vigor. This can lead to selection against hybridization and reinforcement of reproductive isolation, ultimately leading to the formation of new species.
