Yes, but Adam's genes don't segregate exactly the same way each time during meiosis. If we consider it with two genes, one time the fertilizing sperm might be AB. Another time it might be Ab. The thing is, Adam's father/mother chromosomes don't segregate the exact same way each time, unless they have a "destiny"

OK, so I was thinking about time travel the other day, and basically formulated a kind of logic puzzle: The Primary Assumption: Time Travel is possible. Now assuming that the above is true, here's my scenario: Suppose someone (e.g. Adam) is a normal guy. He somehow travels back in time and meets his mother. Adam then marries his mother and has a child, himself. Now, here's my paradox. If he travels back in time, then he would always have been his own father. I know this "time loop" thing has been proposed before and you probably all already know what it is. Now, unless parallel universes exist, Adam is his own father. Let's say Adam Original's genes are XY. X from his father, Y from his mother. However, if he is his own father, won't Adam New have a different set of genes than Adam Original? And if this keeps on happening, every Adam will have a different set of genes. According to the "time loop" scenario, everything should always be the same. However, if Adam fathers himself, his wife/mother's genes will be more and more prevalent in the new Adam's genes. The way I see it, the only way this scenario can work out is if: 1) time travel is not possible, and my original assumption is wrong or 2) every time something time travels, an alternate/parallel universe is created which is different than the old one.
