What are the two major types of reproductive isolating mechanisms?
There 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.Click to see full answer.

There are two main categories of reproductive isolation: prezygotic and postzygotic. Prezygotic isolation occurs before the formation of a zygote can take place.

Hereof, what are the different types of reproductive isolating mechanisms?These include temporal isolation, ecological isolation, behavioral isolation, and mechanical isolation. Post-zygotic barriers: barriers that come into play after two species have mated. These include genetic incompatibility, zygotic mortality, hybrid inviability, hybrid sterility, and hybrid breakdown.Also, what is isolation and its types? The field of biology describes “isolation” as a process by which two species that could otherwise produce hybrid offspring are prevented from doing so. There are five isolation processes that prevent two species from interbreeding: ecological, temporal, behavioral, mechanical/chemical and geographical. Then, what are the three mechanisms for reproductive isolation? Three mechanisms for reproductive isolation are ecological, behavioral, and mechanical.What factor can cause two populations to become reproductively isolated?A geographical barrier can result in allopatric speciation. Some of the common examples of geographical barriers are glaciers, rivers, mountains, lakes, canyons, oceans, and lakes. It is one of the factors that can result in two populations to become reproductively isolated.
