In this study, 23 Y chromosomal STRs (DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS385a, DYS385b, DYS438, DYS439, DYS437, DYS448, DYS456, DYS458, DYS635, YGATAH4, DYS576, DYS481, DYS549, DYS533, DYS570, and DYS643) were investigated in 258 unrelated individuals of Mongolian descent living in the Inner Mongolia Autonomous Region. A total of 233 different haplotypes were found, and 209 of them were unique. Haplotype diversity was 0.9992 and gene diversity ranged from 0.4840 (DYS391) to 0.9679 (DYS385ab). Both Rst pairwise analysis and multidimensional scaling plot showed that the genetic structure of the Mongolian population was significantly different from some Chinese ethnic groups and neighboring populations. It is notable that there were null features existing at DYS448 as observed by the PowerPlex® Y23 System, which could be also obtained by sequencing in the Tibetan population.
