I'm not OP. Can someone with knowledge of genetics explain pic related to me? For example's sake, let's just assume that the children are both 1/4 black. So their black father was half white, and their mother was 100% white.
I'm mixed race myself, and I look like the girl on the left(I'm a dude). I have a fraternal twin brother who, fortunately, looks like the same race as me. As you can see from pic related though, when you are mixed race, there can be a significant variance in phenotype.
So I have two questions. Does the sibling just look different, or from a scientific perspective should she be considered a different race. And if both parents had been mixed race with the same phenotype(a father who was 1/4 black and a mother who was also 1/4 black), would there have been the same variance in phenotype of the offspring?
I think a good example would be light skinned mexicans. There's no way that a light skinned mexican couple could produce a brown skinned bean child, right? Wouldn't the phenotype necessarily stabilize the further down it goes in a mixed race family tree?
