A man from here in Texas came down with Lymphoma. He beat it. He was concerned about his medical history--because his father was not in the picture, so he used a DNA kit: 23 and Me, to do genetic testing and find out what he may or may not be susceptible to. His really good friend decided to also use the DNA kit.
The CRAZIEST thing happened: The two friends found out they are actually HALF-BROTHERS!!
Walter Gordy and Mark Tolson have been friends for 12 years and are actually related. It turned out they were both raised by single mothers, who were each inseminated. The two women chose the same donor. Further, it turns out the two moms actually have known each other for years--they have been singing in the same church choir for years!
