With a new technology such as cloning, little is known about the long term affects that come along with it. Scientists are learning that cloning isn't as simple as they thought when they cloned Dolly. In fact, scientist are amazed dolly had even survived past a few weeks of living. Only 2%-5% of all eggs that end up as clones end up as living animals.The amazing thing about cloning is that even though a clone might have defects, if that clone mates with a regular animal the baby will come out perfectly fine. Dolly has given birth to many normal baby sheep. In my opinion we need to master the art of cloning before any thought is given about cloning humans.
