Admixture analysis, hierarchical cluster tree and PCA plot of TWB and 1000G East Asian samples. (A) Admixture analysis. Individual probabilities for all samples were assigned under the model of four (K = 4) ancestry populations. The samples were clustered into six groups: Japanese in Tokyo, Japan (J), Chinese Dai in Xishuangbanna, China (D), Kinh in Ho Chi Minh City, Vietnam (K) and three Chinese groups (indicated by S, N and T) from TWB, and the Chinese in 1000G, including CHB (Han Chinese in Beijing, China) and Southern Han Chinese, China (CHS). The Han Chinese samples were further clustered into 9 subgroups (T1–4, N1–2 and S1–3) based on the hierarchical cluster tree below. (B) Hierarchical cluster tree based on the ancestry-assigned probabilities for the TWB and 1000G Asian samples. The Han Chinese samples, TWB, CHB and CHS, clustered in three major groups, namely northern Han Chinese (N), southern Han Chinese (S), and an unknown ancestral group of Taiwanese Han Chinese (T), whereas Japanese (J) samples clustered in another group. (C) PCA plot for the TWB, CHB, CHS, JPT, CDX and KHV populations. PC1 and PC2 are the first two components derived from the PCA. The different colours for the samples correspond to their geographical groups (J, D, K, N1–2, S1–3 and T1–4) in the hierarchical cluster tree (Fig 1B). O, others unable to be defined.
