Question

Pre-zygotic isolation means that


A) two organisms never have the opportunity to create a zygote


B) two organisms create a zygote that does not survive after birth

Answer 1

"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." -https://www.sparknotes.com/biology/evolution/reproductiveisolation/summary/#:~:text=Prezygotic%20isolation%20occurs%20before%20the,mated%20and%20produced%20a%20zygote. and my notebook for bio
