I know that criticizing autosomal DNA reports from dnaprints and dnatribes is something of a sport on this list, but they do provide data.
I'm a J2 ydna and K mtdna fellow with pretty good paper trails back to England and Scotland on both sides of my family. Like many families, there were stories of "Native American blood" in a couple of the lines.
I recently had my atdna done by dnatribes. Their service was quick and very responsive. The results were surprising:
Paraiyar (Tamil Nadu, India) 292
Tanjore Kallar (Tamil Nadu, India) 102
Thai 34
Berber 31
Portuguese 30
It then procedes on through several more Indian groups.
The "Continental Match" from dnatribes is:
South Asian 14.1
European 6.4
Latin American 2.4
Omnipop gives similar results. It also lists some moderate matches to some Native American populations and some other Asian and European groups. More details about my results are at Kerchner's dnatribes site.
I asked Thomas Krahn of dnafingerprint about the results and he checked them. (This was amazing service by the way, he went down and looked at the testtube and the electroperogram again, and emailed back what he found in less than 12 hours. I was very impressed and plan to do business with him again.)
As I understand, none of my markers are that rare in Europe, it's just that the combination looks Indian or Asian. "The only odd result is a 34.2 at D21S11." I wonder what to make of all this. I think that the results are too vague to support whether or not my gggrandmother was a Native American.
I also wonder what is going on with the pretty strong Indian look of the markers. I realize that the markers may have been bouncing around in Eurpoe since the Paleolithic. I also realize the pattern should have been recombined out of sight if it had really been in Europe for thousands of years.
Should I be looking for a NPE or some other surprise in the last few generations? Could it be Native American markers. There are a ton of cousin marriages in my pedigree and 3 of my 4 grandparents are second cousins, so it is possible that a pattern could have made it fairly intact through the last couple of hundred years.
