Reproductive Isolation: Pre-zygotic, Post-zygotic, Genetics

The definition of reproductive isolation is “the inability of a species to successfully breed with related species due to geographical, behavioral, physiological, or genetic barriers or differences.”

A crucial component of speciation is reproductive isolation. It refers to the controls that keep populations that are closely related from reproducing with one another, which might eventually result in the emergence of new species. Reproductive isolation can occur before or after conception, and it is typically the consequence of genetic, ecological, or behavioural causes. We shall examine prezygotic isolation, postzygotic isolation, and the role of genetics in reproductive isolation as well as other mechanisms of reproductive isolation in this article.
