Seriously. When I was young a friend of mine who was white was married to a black guy, He was really black. They had a baby and it was a white as the driven snow. Tests were done at his mothers request. She did not believe the child was her grandson. He was. Doctors told them they MUST tell the child that he had black in him, as the chances were if he married a white girl they would have a black baby. To my knowledge Mother and Son fell out over her distrust and have never spoken since.
