Do you remember how careful scientist were in the beginning with genetically altered corn? Well it seems to me that before to long any genes of cloned or genetically altered humans will be mixed back into the sacred untainted gene pool. Won't this be the beginning of a group of mutant genes being released on society. Surely this could have it's assets, but it could also cause some irreversible damage. You know what they say. It's not nice to fool mother nature.
