Abstract

X chromosome exhibits gender-specific genetic patterns, which makes genetic markers on the X chromosome show important values in some complex kinship analyses and population genetic analysis. In this study, we investigated genetic distributions of 19 X-STRs in Chuanqing, Tujia and Yi groups from Guizhou province in China. Besides, population genetic relationship analyses among the three studied populations and other reference populations were conducted by multiple methods. We found the 19 X-STRs showed relatively high genetic diversities in Chuanqing, Tujia and Yi groups in Guizhou province. DA genetic distances, phylogenetic tree and principal component analysis indicated relatively close genetic affinities among Chuanqing, Tujia, Yi, Zuiyi Gelao, Guizhou Bouyei, Guizhou Miao and other geographically adjacent populations.
