Description
English: Plot of Principal Components for 446 individuals representing 15 populations. Individuals are shaded by different colors according to their predefined population affiliations, and the legend is displayed on the lower right of the plot. CHB is Chinese in Beijing, and JPT is Japanese in Tokyo. (A): plot of the first two principle components. (B): plot of the first and the third principle components. Principal component analysis was performed at individual level using EIGENSOFT version 2.0.


As shown in a 2-dimentional plot of first two PCs, individuals tend to cluster with other members of their linguistic or ethnic affiliations. Again, Mlabri showed a closer relationship with the Htin for PC1, which explains 21.8% of variation represented by the first ten PCs. The closer relationship between Mlabri and Htin is even more pronounced in the 2-dimentional plot of PC1 and PC3.
