Abstract: Objective To study the genetic polymorphism of five STR loci on X- chromosome in 98Ewenke population of China and establish the related genetic database. Methods The sequence variationof DXS7423,DXS7424,DXS7132,DXS7133,DXS6804 loci on X- chromosome were analyzed by PCR fol-lowing PAG electrophoresis and silver staining. Results The genetic data of the 5 X- chromosome STRs inEwenke ethnic group of China is in accordance with Hard- Weinberg equilibrium. Conclusion Five X- STRloci could be used in forensic identification and population genetic research.

Key words: X-chromosome, short tandem repeat(STR), genetic polymorphism, Ewenke population
