PC plots of PC1×PC2 (A) and PC2×PC3 (B) generated by projecting the Bangladeshi samples enrolled from two sites in this study (dark green glyphs, labelled as BDD: Bangladeshis in Dhaka; light green glyphs, labelled as BDM: Bangladeshis in Mirzapur) onto the axes of variation derived from the 2504 1000 genomes samples (20130502 phase 3 data release).
