Chimera Twins Story

skelley writes "Below is an audio link on this morning's story on NPR about Chimera twins, or people with two sets of DNA. It turns out that every once in a while a set of fraternal twin eggs merge into one embryo. The resulting person has two sets of DNA. The story says it is possible for a Chimera to have different sets of DNA in different body parts. This can cause complication for body identification, DNA typing for organ transplants, crime investigation, etc. Researchers have no idea how common this is, but suppose that it is a reasonable percentage of all fraternal twin pregnancies, which would mean millions worldwide. No text version. NPR often doesn't publish one. "

lie detectors are not allowed in the court, they are merely used in certain investigations because they are reliable enough to put investigators on to leads.

Nature published a short article on this a couple of years ago that we covered in our Journal Club meeting at my lab.

A short while later, God published an article calling bullshit on Nature, basically saying she was a sensationalist.
