No, A white woman can have black children, but a black woman can never have white children. It's a rule
No, your answer is not exactly correct. A white woman can give birth to a biracial child and a black woman can give birth to a biracial child. I have heard of that rule also, but not all rules are correct.
Because if we used that reasoning than a woman who is half black/half white, could only give birth to a black child even if the father of the child is white. According to the so-called rule, what would Eartha Kitt's granddaughter be considered or what about Victoria Rowell's daughter?
