Which of the following is a postzygotic isolating mechanism?
A) Hybrid infertility
B) Behavioral isolation
C) Mechanical isolation
D) Hybrid zones
E) Incompatibility between gametes

Question

Quizplus · Accepted Answer

Postzygotic isolating mechanisms occur after fertilization and prevent the development or reproduction of hybrid offspring. Hybrid infertility is an example of postzygotic isolation, where the offspring of two different species may be viable but sterile, preventing gene flow between the species. Behavioral isolation and mechanical isolation are prezygotic isolating mechanisms that prevent mating from occurring, and hybrid zones and incompatibility between gametes do not specifically refer to postzygotic isolation.
