Abstract:
OBJECTIVE:To study the genetic polymorphism of five STR loci on X-chromosome in 98 Ewenke population of China and establish the related genetic database.
METHODS:The sequence variation of DXS7423, DXS7424, DXS7132, DXS7133, DXS6804 loci on X-chromosome were analyzed by PCR following PAG electrophoresis and silver staining.
RESULTS:The genetic data of the 5 X-chromosome STRs in Ewenke ethnic group of China is in accordance with Hard-Weinberg equilibrium.
CONCLUSION:Five X-STR loci could be used in forensic identification and population genetic research.
