Detailed explanation-1: -So, the correct answer is ‘zygote development’

Detailed explanation-2: -category in reproductive isolation Prezygotic RIMs prevent the formation of hybrids between members of different populations through ecological, temporal, ethological (behavioral), mechanical, and gametic isolation.

Detailed explanation-3: -Prezygotic isolation prevents the fertilization of eggs while postzygotic isolation prevents the formation of fertile offspring.

Detailed explanation-4: -There are two main categories of reproductive isolation barriers: Prezygotic isolation – occurs before fertilisation can occur (no offspring are produced) Postzygotic isolation – occurs after fertilisation (offspring are either not viable or infertile)

Detailed explanation-5: -Prezygotic isolation occurs before the formation of a zygote can take place. In most cases mating does not even occur. Forms of prezygotic isolation include spatial, behavioral, mechanical and temporal isolation. Postzygotic isolation occurs after members of two different species have mated and produced a zygote.
