Interesting question.....?

Everybody has dominant and recessive genes, so to my way of thinking, if a human was able to self fertilize and reproduce, the product (baby) COULD be an exact replica but wouldn't necessarily HAVE to be, because of all of the dominant and recessive genes. If the product (baby) recieved the exact mix of genes that the mother recieved, then yes, it would be a replica, but like the other poster said, it would *kind of* be like the person's mother and father having another child. With the exception of identical twins, most siblings look alike, but are not identical, and some don't even look like each other...
