Child Fathered by Dads Unborn Twin

It may sound like a bad episode of Maury, but a Dad discovered that his new son was actually fathered by a brother he didn't know he had. Confused? Well, this story, as crazy as it may sound, is true. As reported by Newser, a couple who used a fertility clinic to conceive their child in 2014, was concerned when they discovered that they had a different blood type than their son. They decided to take an at home DNA test, and the father learned that his DNA did not match his sons. Understandably upset, they accused the clinic of using the wrong sperm sample. The clinic, believing they did not mix anything up advised the family to take a DNA ancestry test.

As it turns out the father of the boy was his uncle. In something out of a movie, the dad was a "human chimera." Human chimera, is what happens when one baby soaked up the genes of a twin that perished int he womb, allowing the dad to pass his unborn genes to his son. Apparently, this is more common than you would thing, however, it's just not very well knows because it is not easy to identify, unless individuals are involved in situations like this.
