Darwin Fenton bio

Why do I have a bad feelings about this ???
So...this is Darwin Fenton, another OC of mine. About his look...I took some advice from my mom yesterday, and this is how it turned out. If you have any question, feel free to ask. And now I will explain why can Darwin got his power so early. PLEASE READ THIS CAREFULLY, OK ??? OK. And the bio too !!!
It might get a little hard to understand so read carefully !!!
According to my Biology textbook, this case CAN be happened logically. Let just say Danny's human characteristicts are Aa, and the ghost characteristics are Bb, cuz he's a halfa, for short is AaBb. Sam's is Aabb (cuz her ghost gene from the episode Urban Jungle isn't quite gone all). When combine AaBb and Aabb together, we have these gameteses :
+G: AB, Ab, aB, ab (Danny) x Ab, ab (Sam)
+Result: AABb, AaBb, AAbb, aaBb, Aabb, aabb (check again yourself)
In Darwin case, it's AaBb. In Esmerelda case, it's Aabb, with Bb is 50% and bb is 0% or 25%.
Any question ???
Darwin (c)
