in some zoos, rare crosses between a male lion and a female tiger have produced hybrid offspring cal are sterile but some female ligers are fertile. In the wild, lion and tige unlikely. Furthermore, the solitary behavior of tigers and the social organizations of lion hybrid offspring called "ligers." Male ligers r ranges do not naturally overlap, making such a cross s create behavioral difference 6) Applying the biological species concept, the sterility of ligers reveals that 6) A) tigers and lions are separate species B) a new species called "ligers" is forming C) lions are probably a subspecies of tigers D) tigers and lions are actually the same species 7) The production of sterile male ligers is an example of 7) A) a prezygotic barrier C) the founder effect B) sympatric speciation D) a postzygotic barrier 8) S) Examine the figure below. According to the figure, cladistic analysis indicates that crocodiles are 8) 8) more closely related to- than to .- and snakes e Crocodilians Pterosaurs Commorn ancestor of crocodilians, dinosaurs and birds omithischian Omithischian Saurischiarn dinosaurs Birds A) snakes... birds C) Ornithischian dinosaurs... pterosaurs B) birds... pterosaurs D) birds... lizards 9) Biological species consist of groups of 9) A) genera B) families C) populations D) domains 10) Under the biological species concept, what criterion is used to assign populations of organisms to 10) the same biological species A) responding to the environment in the same way B) a very similar appearance C) having 99% of their genes in common D) being able to interbreed and produce fertile offspring
