answer:Well, if you're talking about genetic clones, explore the nature vs. nurture question, as well as the fact that if I were to clone you, your clone would start out as an infant. That clone may have a striking resemblance to you, but would be a completely distinct consciousness, and as he would be raised in a completely different environment would think, act, and speak differently than you. (Also check out some studies on twins who were separated at birth-- a surprising number of things seem to have some genetic basis)
