Factual Questions

Just read a weird story on ananova

http://www.ananova.com/news/story/sm_838312.html?menu=

It’s basically about a woman who it states is a chimera of two non identical female embryos that merged in her mother’s pregnancy. As Ananova is not always the most reliable of news providers are there any geneticists out there who can confirm or refute the facts of this story?

The story orginally comes from the New Scientist (you can read it at there website if you’ve got a susbscription), here’s a BBC article:

I’m not a biolgist, but I have heard of chimerism in humans before.

Hmm, could make an intersting CSI episode. Skin DNA found at the crime scene doesn’t match blood DNA for the suspect…

talked about it a while back. One of the examples was a woman who wasn’t directly related to the sons she had born.

Her blood and skin have different sets of genes.

Morning Edition talked about it a while back. They talked to a woman who wasn’t directly related to the sons she had born.

Her blood and skin have different sets of genes so wouldn’t match in a DNA test
