Where did you read this about the father, because I've heard him talk about his childhood experience of basically living with the half of his family that was all black and he didn't even understand his skin color was different. If there were white people in the room or the family, I doubt he would have said that (that he was a unicorn, only light skin person).
And for all the talk on this board of what people should look like (not referring to you Patsgofor4) I have a friend who looks totally white, white complexion, straight hair, but his mother is 100% black with dark skin. My friend married a white woman, their first son looks like the mother, the second son is much darker than the father and has curly hair.
So, many assumptions are being made here that totally ignore genetics.
