Prezygotic isolating mechanisms prevent the formation of zygotes between different species. Ecological isolation, temporal isolation, and mechanical incompatibility are all examples of prezygotic isolating mechanisms. Prevention of gamete fusion is also a prezygotic isolating mechanism, as it prevents the fusion of gametes from different species. However, hybrid sterility is a postzygotic isolating mechanism, as it prevents the offspring of different species from being able to produce viable offspring of their own. Therefore, option D (hybrid sterility) is not an example of a prezygotic isolating mechanism.
