Quizplus · Accepted Answer

Hybrid sterility is a type of postzygotic reproductive isolating mechanism in which the hybrid offspring between two different species are sterile and cannot reproduce with either parent species. This mechanism prevents gene flow between species and contributes to their divergence over time. Temporal isolation, mechanical isolation, and behavioral isolation are examples of prezygotic reproductive isolating mechanisms that prevent the formation of hybrid offspring in the first place, while sexual deselection is not a recognized type of reproductive isolating mechanism.
