Good to hear from you too.. MY only point in this... is this is a newbee list... and although, some of you into biology know the difference, between saying some thing creates the sex of a person and something is sex-linked. Others do not.. to include myself when I first started.
I thought mtdna was the female sex chromosome.. how else could they get dna from it to test.. then I learned!!! ... then my next suprise was that not all chromosomes were held within the nuculas.
MTDNA because it has is its own cicular dna string is considered a chromosome. it is the dna within the mtdna that allows it to be tested. Because it is passed almost unchanged and has no recombination as the X sex chromosone does, it is used for identifying the female in the case of genealogy.
And when they ever get the kinks out of autosomimal testing... It will open a world of research for all of us..
