उत्तर

A prezygotic isolating mechanism prevents successful zygote development.

Explanation:

Some textbooks classify isolating mechanisms that act after mating but before a viable zygote forms as prezygotic. In such cases, sperm may enter but the zygote fails to develop, so no successful zygote is formed.
