Well, I have no idea on earth why your own DNA would not match your own DNA! Who proposed that idea?

Now, if you're talking about why a rootless hair from your head would not match your blood... well, the hair from your head would have only mitochondrial DNA (from your mother only) while your blood (or saliva) would have DNA inherited from both your parents. That's why they wouldn't "match" exactly.

Your reply is above. I am talking about the MH sink drain trap hair with root (nuclear DNA, right?) matching 12 of 13 loci to the DNA extracted from Danielle's rib. Holland (?) the DNA guy said so.

Why doesn't it match exactly?
