which they need not be.

There is enough data of Native Americans publicly available at the
Stanford cell line project web site, and, if you want a near-perfect match
in markers with 23andme (Excluding markers unique to them) they
exist on the Illumina data site also.

There are two populations, Maya and Pima, in North America,
and three in South America too.

I am using them in my BGA programs. They have successfully found
3-5% levels in people who expected them. I have not tested anyone
who expected more than that.
