A type of isolating mechanism that leads to reproductive isolation after a hybrid zygote has formed is called _____________ isolating mechanism.

Question

Quizplus · Accepted Answer

Postzygotic isolating mechanism refers to the barriers to reproduction that occur after the formation of a zygote, which may be non-viable, sterile, or have reduced fitness. This type of isolation occurs after hybridization has occurred. Prezygotic isolating mechanisms, on the other hand, prevent the formation of a zygote, while adaptive and differential isolating mechanisms are not specific categories of mechanisms. Hybridization is a process of interbreeding between two different species or genetically distinct populations, and not a type of isolating mechanism.
