From what I heard it's not the tests themselves, it's the mathematical models used to interpret the results.

Lawyers are getting some good business out of Chimerism too!
The DNA of Fairchild's children matched that of Fairchild's mother to the extent expected of a grandmother. They also found that, although the DNA in Fairchild's skin and hair did not match her children's, the DNA from a cervical smear test did match. Fairchild was carrying two different sets of DNA, the defining characteristic of chimerism.

One day I hope to have some fun with DNA evidence but I need the right fact pattern to do it.

Yeah that appears to be the case. I suppose that today, if everyone gave two samples of DNA under different names, we would all be chimeras

Bear in mind too the commercial tests that you take at home are not up to the standards of a 'CSI' lab.

You mean like the Illinois Crime lab that convicted over 100 people to death with fake DNA evidence? That is in fact when I decided I was against the death penalty, as there are no undos.

I should qualify that as my own experience in Canada.
