WebOct 29, 2024 · It looks like there are five major types of prezygotic barriers to reproduction: spatial isolation, temporal isolation, mechanical isolation, gametic isolation and behavioral isolation. What is Prezygotic barrier in biology? Prezygotic barriers prevent members of different species from mating to produce a zygote, a single-celled embryo. WebThere are two main categories of reproductive isolation: prezygotic and postzygotic. 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.
