Homework Answers
The answer is C.
Gametic isolation.
explanation
Hybrid sterility is the prevention of capacity to reproduce in hybrids that usually belongs to different species. Gametic isolation is a prezygotic barrier in which the reproductive cells gets in contact, but fertilization won't occur. Specific proteins present on the reproductive cells permits them to recognize each other & these specific proteins are different in each species. This is one of the reason why reproductive cells are unable to fuse to form zygote in case of gametic isolation.
hope it helps.

Required information For each of the questions in this series, determine which reproductive barrier each situation describes. Then, determine if the reproductive barrier is a form of prezygotic or postzygotic reproductive isolation. Click on the box in the table that matches both criteria. For example, if you think the situation describes behavioral isolation, and you think behavioral isolation is a postzygotic reproductive barrier, then your answer should appear as below: Prezygotic barrier Postzygotic barrier Habitat isolation Temporal isolation Behavioral isolation...
