The cloned baby would grow up to look just like its genetic parent, but wouldn't necessarily have the exact same personality. That's because personality is heavily influenced by life experience and environment. As the cloned baby grows up, it will have its own memories, dreams and thoughts. The clone would, in most legal cases, have the same rights as a baby made the old-fashioned way. So, while you're spending your teen years listening to Limp Bizkit and Eminem, your clone could grow up to be the biggest fan ever of a future boy band.
Some people have serious doubts about whether cloning humans is a good idea.
It raises a ton of legal, moral and ethical questions. Other people just think cloning sounds kind of spooky, and is not something humans should mess around with. Some people fear that clones could give rise to a race of superhumans - a world of cloned superstars, athletes, Nobel Prize winners and beautiful people. Just because we can do it, they say, doesn't mean we should. But researchers say the scientific knowledge necessary to clone a human is out there, and cannot be stopped.
