While the dark-skinned boy did eventually meet the man who was his biological father, the brothers consider themselves full twins. One of them was black.īeing of different races and coming from different fathers hasn’t stopped the Stuart boys from closely bonding. The couple remembers two other couples in the waiting room the day of the procedure. The hospital called it a “deeply regrettable mistake.” It soon became apparent that a device similar to a large eyedropper had been used twice, causing another man’s sperm to be mixed with Willem’s. However, after about a year, genetic tests revealed that while one of the twins was biologically related to both parents, the other twin was not. The parents, who are both Caucasian, were mystified when the twins were born, but fell deeply in love with both of them. In 1993, another set of black and white twins was born to the Dutch couple, Wilma and Willem Stuart, but it turned out to be a case of an in-vitro mix-up. Knight is of Jamaican and English descent the father is German. Knight’s older daughter has blond hair, blue eyes and light olive skin.
BLACK AND WHITE TWINS SKIN
Natasha Knight, of Australia, welcomed a blue-eyed blond baby girl and her sister, who has brown hair, eyes and dark skin in 2006. In the past few years, at least three mixed race couples have welcomed twins who were also black and white. Rare though they are, the German twins do have some company. Very occasionally, the roll of the DNA die may cause the baby of biracial parents to inherit only the genetic coding for one color.

Peter Propping, former director of the Institute for Human Genetics at Bonn University, told Die Welt that the black mother may have had some white ancestors, or that the white father may have had black ones. The odds are one in a million, say doctors, but it can happen with fraternal twins due the genetic soup in our backgrounds. VIDEO: These brothers are a very rare pair It was “a real surprise,” Gerth told the German newspaper Die Welt, adding that the most important thing to him isn’t color, but that everyone is healthy. His wife, Florence Addo-Gerth, is from Ghana and has dark skin. "Both kids have definitely the same father." "None of us could believe it," the maternity ward's head doctor, Birgit Weber, told one news source. His brother, Leo, is dark-skinned with brown eyes. Mum Alison, a 37-year-old office manager, said: “I can’t believe my miracle babies are turning 18.The first baby that was born, Ryan, has light skin and blue eyes. They remain the world’s only two sets of twins in one family with different skin tones. Simon Fishel, head of Care Fertility Group clinic, said: “What is really remarkable is this has happened in two sets of twins in exactly the same way.”īut in a further remarkable twist, seven years later they found their way into the Guinness World Records book when their younger twin sisters Leah and Miya, who are now ten, were also born with one white-skinned and the other with a darker complexion. They can be born with different skin colours when two separate eggs are fertilised by two sperm, meaning they each have a different genetic inheritance from their parents. Non-identical twins share around 50 per cent of their genetic make-up. It is always possible for a mixed-race couple to have a white or black child depending on their dominant and recessive genes. A MIXTURE of several genes is believed to determine human skin tone.
