London: A black couple has amazed genetics experts, as their newly born baby is a white, blue-eyed blonde.
Doctors at Queen Mary`s Hospital in Sidcup told the parents that Nmachi Ihegboro is definitely no albino.
However, the child has baffled the genetics experts because neither Ben nor wife Angela has any mixed-race family history.
Professor Bryan Sykes, head of Human Genetics at Oxford University and Britain`s leading expert, called the birth ‘extraordinary’.
"In mixed race humans, the lighter variant of skin tone may come out in a child - and this can sometimes be startlingly different to the skin of the parents,” the Sun quoted Sykes as saying.
"This might be the case where there is a lot of genetic mixing, as in Afro-Caribbean populations. But in Nigeria there is little mixing," Sykes added.
Sykes said both parents would have needed "some form of white ancestry" for a pale version of their genes to be passed on.
But he added: "The hair is extremely unusual. Even many blonde children don`t have blonde hair like this at birth."
The expert said some unknown mutation was the most likely explanation.
"The rules of genetics are complex and we still don`t understand what happens in many cases," he added.
