Types of Reproductive Isolation
Behavioral isolation is a type of prezygotic barrier that prevents interbreeding between closely related species because there is no mate recognition between females and males of the different species.
Reproductive isolation The environment may impose an external barrier to reproduction, such as a river or mountain range, between two incipient species but that external barrier alone will not make them separate, full-fledged species.
One prezygotic reproductive barrier is temporal isolation. Temporal isolation means 'isolated in time,' so this is a mechanism that prevents species from mating because they breed at different times. These differences can be time of day, season, or even different years.
Reproductive isolation is why different species of animals and plants are not able to interbreed with one another. Speciation, or when one species splits into two or more species, is to be blamed for many cases of reproductive isolation within similar types of organisms.
