I mentioned a few days ago that a friend was trying to get together some data to analyze the genetic variation of South Asians. By a strange coincidence Dienekes just published a more detailed analysis of South Asians...and uncovered something very interesting, though not that surprising. Some technical preliminaries:
A note of caution: The reduced marker set (~30k) means that a lot of noise is added in the admixture estimates. In particular, many individuals are likely to get low-level admixture from population sources that can be attributed to noise. But, as we will see, the small marker set does not really affect either the power of the GALORE approach, or of ADMIXTURE to infer meaningful clusters.
In addition to the various online sources of public data Dienekes got about a dozen South Asians. I was one of those South Asians, DOD075. In many ways I'm a rather standard issue South ...
