Reply to comment by SweetBasil_ in Why don't we have Neandertal mitochondrial DNA? by nodeciapalabras

So matching mitochondrial DNA doesn't actually mean much in the context of forensics then, because you could also match with your 13th cousin 6 times removed and for all you know there are 17 of them in your village?

(I am zero surprised a TV show is wrong about science, by the way.)

When you use DNA to match to a suspect, you usually use short tandem repeat (STR) length patterns in nuclear DNA, which change more frequently than nuclear DNA by several orders of magnitude.

There are multiple episodes specifically about matching mitochondrial DNA with the suspect's mother, which was my specific question. :)

should definitely get a nice match with a mother, but i wouldn't put anyone on death row based on that alone :)
