Fig. 2. Principal component analysis (PCA) of the 16 probands together with the 2504 individuals of the 1000 Genomes Project (Phase 3).
Individual NA10851 is plotted twice for quality control purposes, having been genotyped both within the 1000 Genomes Project (NA10851_1KG) and in-house (NA10851_internal). The proband clustering within the smear of native Americans is A228.
