I think so too. OmniPop and the RCMP employ established databases
published in the technical literature and I'm sure the analysis
conducted (the results) are correctly done. Also even though OmniPop and
the RCMP use different numbers of populations (OmniPop uses 202
populations I think, and the RCMP a far smaller number) they both gave
similar results in the cases I tested (so far as it goes). In my case,
as I said, I thought the results were accurate in terms of recent
heritage. They didn't agree, weren't even close, to the Y-DNA results
and I didn't expect them to be. The Y-DNA says I'm J2a1* which means a
Middle Eastern population and I find alot of close matches too with
Eastern European peoples and populations from the coastal areas of the
Mediterranean Sea. My mtDNA is haplogroup C which is a native of the
Americas. I thought since my recent heritage for the last 500 years at
least has been all in the Americas (more NA than European) that my
autosomal markers, a mixture of maternal & paternal lines, would show
that recent heritage and they did, very clearly. When I tested my
paternal Uncle (our Y-DNA matches exactly on as many markers as I could
test) I expected to see a shift in the NA population groups because he
is mtDNA A, and I did. It was great!

Well, maybe I got lucky, I don't know, those results just made great
sense. When the results seem screwy though it doesn't mean that we
should slam OmniPop or RCMP as Mr Greenspan did, it just means we have
to dig deeper to find out what is going on ...
