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 passion...claims 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%. )
