From: Low Levels of Genetic Divergence across Geographically and Linguistically Diverse Populations from India Rosenberg NA, Mahajan S, Gonzalez-Quevedo C, Blum MGB, Nino-Rosales L, et al. PLoS Genetics Vol. 2, No. 12, e215 doi:10.1371/journal.pgen.0020215 [1] (fig. 2A) original caption:

" Representative estimate of population structure for 1,384 individuals from worldwide populations, including 432 individuals from India. The plot represents the highest-likelihood run among ten STRUCTURE runs with K = 7 clusters. Eight of the other nine runs identified a cluster largely corresponding to India, and five of these eight produced plots nearly identical to the one shown."
