Harappa Ancestry Project, t-minus one day

Zack is going to post the first batch of results from HAP tomorrow. It looks like he’s going to be using mostly the merged HGDP, HapMap, SVGP, and Behar data set, supplemented by a second set which also merges the Xing et al. sample (the intersection of Xing et al. with the other results is a much smaller number of SNPs, but, it includes a better coverage of various South Asian groups). He’ll initially be posting ADMIXTURE estimates as you’ve seen on Dodecad. I’m especially interested in the Anglo-Indian and Roma individuals which have sent Zack their samples. I don’t know of any genomic investigation of the former community, while the published research on Roma genetics doesn’t include SNP-chip results (usually they’re mtDNA, Y, or only a few autosomal markers). I’d be curious for possible evidence of homozygosity or linkage disequilibrium in the Roma individual due to the population bottlenecks which other studies have detected (I assume that’ll be in the future). The Roma are to a good approximation an admixture of India, West Asia, and European (often Balkan) groups, but, their history of endogamy and …
