WebReproductive barriers can be divided into two major categories: pre-zygotic or post zygotic. The former is an issue that arises before fertilization such as two animals not being compatible anatomically or a behavioral incompatibility (think of bird mating rituals, or imagine a mouse trying to reproduce with a whale).
