Or maybe our level of understanding DNA and how it works.

I've always been curious about DNA tests ever since I read about a woman who was about to lose custody of her children (can't remember the reason) because her DNA did not match theirs. Her ex-husband was even in her corner, saying he had watched them come out of her body. Finally it was discovered that she was a genetic chimera; she had 2 different sets of DNA in her body because (they think) she had absorbed a twin in utero. Her uterine DNA was different than her oral DNA. Scientists claim it is a rare condition, but how do they know? It's only been in the last 5 years that DNA testing has become commercially available. We don't know what we don't know.
