Reproductive biology is a fairly well-understood field although it's possible that magic on Equestria could vary things. What we do know is any zygote emerging from breeding has 50% of the genetic heritage of both donors although the specific parts inherited are random. However, they wouldn't be '100%' the same as either donor, only have a genetic heritage dominated by one side or the other or, on rare occasions, equally balanced between the two.
