Can Alien Hybrids Give Birth to Human Babies?

Ok so I couldn't go to bed without testing a few more generations in HAHA. So basically I just had my hybrids keep having kids with full humans for like 4 generations. I would stop and test each generation to see if they could have alien babies. It seems like chances get slimmer and slimmer the further into the generations you go without having a kid with another hybrid, but the hybrid trait seems to get passed on through the generations since in each generation that I had two hybrids have a baby, they eventually were able to have a full powered alien baby. So like 4 generations removed from that second generation hybrid I posted about above, their decedents still have a trace of that hybrid gene and can have a small chance of having an alien baby if they get together with another hybrid (I had to make them have like 6 babies before they got an alien baby, but it is possible!) I feel like I tested deep enough to be satisfied, at least for now ;)
