How Is It Possible For Black Parents To Have A White Biological Child???

My best friend is black and she is married to a black man. They have 2 children that obviously look like their of African ancestry. Their 3rd child their youngest came out looking completely caucasian. They at first believed that wasn't their child and took several paternity test that all came out positive with them being the parents of that child. It made no sense since the baby looks like the average white baby blonde strait hair, white skin, small lips, and big blue eyes. The parents don't have any of these features at all and their not even light skinned black people they are dark skinned black people. The doctor told them that their child isn't albino and may get darker when he gets older. Well he's 7 years old right now and looks nothing likes his parents or his older siblings. He doesn't even look biracial he looks pure white there's nothing about him that looks like he's black. Well he's obviously black since both of his parents are. So how did this happen?

Best Answer - Chosen by Asker: It is entirely possible but extremely rare for this to happen. Both parents must have white ancestors not so far back in their family. It would appear that the "white" DNA hooked up this time. There are some documented cases of twins where one baby is black and the other white (two particularly darling ones in England come to mind) and there was one case in South Africa where white parents had an obviously black child - they had some serious problems because of apartheid.
