Some things arent always black and white. Then again, sometimes they are like the twin sons born July 11 to a German couple.

The first baby that was born, Ryan, has light skin and blue eyes. His brother, Leo, is dark-skinned with brown eyes.

"None of us could believe it," the maternity ward's head doctor, Birgit Weber, told one news source. "Both kids have definitely the same father."

Stephan Gerth is German and white. His wife, Florence Addo-Gerth, is from Ghana and has dark skin.

It was a real surprise, Gerth told the German newspaper Die Welt, adding that the most important thing to him isnt color, but that everyone is healthy.

The odds are one in a million, say doctors, but it can happen with fraternal twins due the genetic soup in our backgrounds. 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. Very occasionally, the roll of the DNA die may cause the baby of biracial parents to inherit only the genetic coding for one color.

 

Rare though they are, the German twins do have some company. In the past few years, at least three mixed race couples have welcomed twins who were also black and white.
