Really interesting blog. A maternal uncle of mine had some time back done this, should ask him for his results!
Would be interesting at some point of time to do this for myself. But being Indian, chances are we will be 100% from here. I wonder if they will give a breakup of ethnicity within India itself
I have that concern too of there not being substantial data for elaborate reports in the minority (minority?) parts of the world... like Africa where I am in.
When I get home this evening I'll try to post a list of the 42 ethnicities they currently cover.
