Figure 5. Three East Asian Populations.

Plots of the first two eigenvectors for a population from Thailand and Chinese and Japanese populations from the International Haplotype Map [32]. The Japanese population is clearly distinguished (though not by either eigenvector separately). The large dispersal of the Thai population, along a line where the Chinese are at an extreme, suggests some gene flow of a Chinese-related population into Thailand. Note the similarity to the simulated data of Figure 8.
