Abstract:
OBJECTIVETo investigate the genetic polymorphism and applied value in forensic medicine of five short tandem repeats (STRs) loci(DXS7130, DXS7132, DXS7133, DXS6804 and DXS8378) on X-chromosome in Achang ethnic group.
METHODSAllele frequency and genotype distribution of five X-STR loci among 100 unrelated individuals from Achang ethnic group were analyzed by PCR following polyacrylamide gel electrophoresis and silver staining. Hardy-Weinberg equilibrium of females was tested and forensic parameters were calculated.
RESULTAll the five STR loci were polymorphic in Achang ethnic group. Chi-square test indicated that genotype distribution of females was in accordance with Hardy-Weinberg equilibrium.
CONCLUSIONThese results enrich Chinese genetic database and can be applied to individual identification, paternity testing and population genetics.
