| Abstract: | To investigate genetic diversity in Chinese populations, 706 unrelated male individuals from five ethnic groups (Han, Korean, Hui, Mongolian, and Tibetan, respectively) were analyzed with 17 Y‐chromosomal STRs. The haplotype diversity was 0.99985 in the combined data. A total of 675 distinct haplotypes were observed, of which 649 were unique. Y‐chromosome haplogroups in the five groups were also predicted with Y‐STR haplotypes. Genetic distance between the five studied ethnic groups and other published groups was analyzed by analysis of molecular variance and visualized in a multidimensional scaling plot. In conclusion, the 17 Y‐STR loci are highly polymorphic markers in the five groups and hence are very useful in forensic application, population genetics, and human evolution studies. |
