A type of isolating mechanism that leads to reproductive isolation by preventing the formation of hybrid zygotes is called _____________ isolating mechanism.

Question

Quizplus · Accepted Answer

Prezygotic isolating mechanisms prevent the formation of hybrid zygotes by inhibiting mating or fertilization. This includes mechanisms such as habitat isolation, temporal isolation, behavioral isolation, mechanical isolation, and gametic isolation. Postzygotic isolating mechanisms, on the other hand, prevent the development or survival of hybrid offspring, and include mechanisms such as hybrid inviability, hybrid sterility, and hybrid breakdown. Adaptive and differential mechanisms are not specific types of isolating mechanisms.
