  • ok, I am not a genetic expert but considering no one has answer this yet I will pass on everything that I know from GCSE biology. Presuming the original parents were fully 'white' and fully 'black' they would have had the genes WW + BB. Therefore, the child would have either WB or BW genes - causing a 'mixed' skin tone. The Children of the child and a white men would then either have the genes WW (white), WW (white), BW (mixed), BW (mixed). I am not to sure whether olive is BW or WW, presuming olive means the child (it's the same for both olive children) has some black genes (BW/WB) then her child with a white man could have the genes WW, WW, BW, BW - giving a 50% chance of a white child, 50% chance of a mixed child, and 0% chance of a black child. The fair blonde will have 100% chance of having a white child, and if the olive children are white, rather than mixed (which is impossible to tell by looking) these odds would be the same. HOWEVER mutations can occur, this is a very simplistic approach and genes really are very complicated. It is also important to remember, white children can have dark skin, and Black children light skin, this doesn't mean they arn't fully black or fully white, they just have natural variations (such as the olive kids, it is impossible to tell) I hope that makes sense, it's a bit hard to describe.
