If you didn’t know any better, you might think that Star, Snuppy, CC and ANDi were just a bunch of interesting names. You’d only be half right These creative names【C1】______ belong to a pig, a dog, a cat and a monkey that were among the first clones of their species.

Cloning may have【C6】______ uses besides its ability to help farmers【C7】______ breed quality burgers and bacon. Other potential uses【C8】______ the preservation of species, biomedical research, drug and organ production and even commercial ventures.
