Reading human hair color, a question popped into my head. Is black eumelanin biochemically unstable or incomplete dominance? I mean, one parent may have only black hair, and that black hair is bred true because of ancestry. Another parent may have brown hair, but carries the blonde allele; and the person may have other genes that control the amount of brown eumelanin throughout one's age. When they cross, the offspring may have some shade of brown or even blonde hair, maybe even black hair. I am not sure if the black eumelanin is actually more biochemically unstable so the brown version takes over or if there is some kind of incomplete dominance going on. 50.4.236.254 ( talk) 15:32, 3 September 2017 (UTC)

Anybody know the name? I would really like to add it to my garden! Wikigirl97 ( talk) 20:35, 3 September 2017 (UTC)
