Read the following scenario to answer the following question. in some zoos, rare crosses between a male lion and a female tiger have produced hybrid offspring called "ligers." male ligers are sterile but some female ligers are fertile. in the wild, lion and tiger ranges do not naturally overlap, making such a cross unlikely. furthermore, the solitary behavior of tigers and the social organizations of lions create behavioral differences. applying the biological species concept, the sterility of ligers reveals that a. lions are probably a subspecies of tigers b. tigers and lions are the same species c. a new species called "ligers" is forming d. tigers and lions are separate species
The production of sterile male ligers is an example of a Post-zygotic barrier
Post-zygotic reproductive barriers is a process that occurs after the formation of the zygote, which denotes reduced viability (the ability to avoid dying) or the reproductive capacity of the said hybrid offspring.
