Population Data


We analyzed Chinese Miao population samples (n = 268) from Guizhou province, Southwest China, with 19 X-chromosomal short tandem repeats (STRs) included in the AGCU X19 amplification kit. The combined PE is 0.999999922 and the combined PDs in males and females are 0.9999999999999999999994 and 0.9999999999998, respectively. The mean paternity exclusion change values are larger than 0.99999996. The HDs in seven linkage groups vary from 0.9324 to 0.9968. Subsequently, comparison among different Chinese populations shows that the substructures of Chinese were significantly influenced by ethno-linguistic rather than geographical boundaries, including most prominently Turkic-speaking and Tibeto-Burman-speaking populations.

Genetic affinity and differences between the Guizhou Miao and 12 Chinese reference populations based on the genetic variants of 19 X-STRs. (A) Principle component analysis was done by the genetic variances of PCA1 and PCA2. Multidimensional Scaling Plots (B) and Phylogenetic Neighbor-Joining tree (C) were constructed based on Nei’s genetic distances matrix. (PNG 470 kb)
