Principal component analysis for 237 samples from Asia for three SNP datasets (A: intergenic SNPs, B: LD1, and C: LD2). The analyses were carried out using LEA. For each PCA, the x- and y-axis refer to the results of the first two principal components (PC1 and PC2, respectively), with each percent variance reported in parentheses. The dots identify the samples. The color of the dots refers to the country of origin (see legend on bottom right). The ellipses on each panel mark each geographical region in Asia, covering 80% of the samples. The colors of the ellipses identify the region (see legend on bottom right)
