here's what I find really strange....unless Rambaldi left his semen in that sample, the child CANNOT be a combination of Sydney and Rambaldi. Reproductive cells are a very special type of cell that only have half of the genetic info in order to merge sperm + egg. If that is just regular Rambaldi DNA, like muscle tissue, then what would end up happening is the child would be RAMBALDI's CLONE! They would clear the genetic matter out of Sydney's egg (which could be done with ANYONE's egg) and put Rambaldi DNA in it, zap it with a current, and voila! Milo Rambaldi a la carte! Therefore, the baby would never be Sydneys.
