In one case the White mother had slept with an African American man and a White man within a couple of hours of each of them. Both of them fertilized an egg.

In another case the father was bi racial--Black and White. Two of his sperm fertilized two eggs. One of his sperm was dominate with his White heritage, the other with his African American heritage. DNA showed that he was indeed the father of both twins.

There was also another case where the parents were both obviously White. But genetic testing then showed that one of them (I forget which one) did have some African American heritage going back years.
