Figure 2

Genetic distances for Y-chromosome data. A neighbor-joining network depicts the genetic distance estimates between South Indian castes, Europeans, and East Asians for 32 Y-chromosome SNPs. The pie diagrams indicate the proportion of each major Y-chromosome lineage found in each population. The inset shows the proportions of Y-chromosome R sub-lineages. Inset circle size is proportional to the total number of R lineages.
