Genetic diversity at 10 X-chromosome STR loci has been approved and widely used for forensic science field. In this paper, we have studied this genetic diversity in various Mongol ethnic group with geographic backgrounds. Allele frequencies of 10 X-chromosome STR loci, including DXS7133, DXS6799, DXS8378, DXS7423, DXS6804, HPRTB, DXS7424, DXS7132, DXS6789 and DXS101, were obtained from healthy unrelated individuals (53 females and 47 males) of Mongol ethnic group lived in north China. Gene diversity analysis showed that the average heterozygosity was uniformly high (0.687) in the studied population. The coefficient of PIC was 0.99998.
