I have a buddy majoring in forensic science, and I was talking to her about this a while back (funny though, she despises CSI with a it doesn't accurately reflect forensics).

Anywho, when DNA tests are done, these days, it is the mitochondrial DNA that is tested. This because almost all of mitochondrial DNA is 100% identical to the mother's mitochondiral DNA, and the rest (which is less than 1% of the DNA strands) is 100% identical to the father's mitochondrial DNA.

Why is this wrong really?
I don't know about forensics but I thought if you used STRs, and one person has 50% of the "bends" the other has they are related being members of one family? (brothers might have more then 50% "identity", children and parents are 50%. )
