An Arizona state crime lab analyst discovered that two felons had very similar genetic profiles.
The men matched at nine of the 13 locations on chromosomes, or loci, commonly used to distinguish people.Of course, mug shots can be deceiving.
The FBI estimated the odds of unrelated people sharing those genetic markers to be as remote as 1 in 113 billion. But the mug shots of the two felons suggested that they were not related: One was black, the other white. [Link]
Some things aren’t 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." [Link]

It certainly wasn't a genealogist who implied that because one was black and the other was white they couldn't be related!
Nor was it Barack Obama.
