Alien Genetics

I've found some interesting things with alien genetics. A full alien and a half alien/half human have two children. The first received an alien birth certificate. When he aged up to a toddler, I tried the alien disguise just to see what he'd look like. In his alien form he is green like his full alien dad, but in his disguise, he's a pale blue, almost white, like his mom, the half alien.

Their second child received a human birth certificate. He's green too. Still a baby, but I'm guessing he'll have hair and be a half alien.
