Biologists divide mechanisms of reproductive isolation into

Biologists categorize mechanisms of reproductive isolation into two main types: prezygotic and postzygotic barriers. These classifications help explain how different species prevent mating and fertilization, thus maintaining their genetic integrity. Can you provide examples of each type of barrier?

The correct answer will be- prezygotic and postzygoticExplanation:Reproductive isolation is the mechanism of speciation which suggests that species gets isolated and do not mate due to reproductive barriers.These barriers could be the pre-zygotic barriers which represent the barrier before the formation of the zygote that is fertilization of the egg and sperm. The post-zygotic barrier represents the condition in which the species are isolated due to barriers arisen due to formation of the sterile offsprings.Thus, pre-zygotic and post-zygotic is the correct answer.
