%X Genetic distribution for nine STR loci was determined in a Chinese Dongxing ethnic group based on STR genescan marked by fluorescence. Seventy-two alleles and 182 genotypes were observed in 94 unrelated Chinese Dongxiang individuals,with the corresponding gene frequency and genotype frequency being 0.0053-0.5825 and 0.0106-0.2660 respectively. The genotypes of nine STR loci were in accordance with the Hardy-Weinberg equilibrium (P>0.05). The statistical analysis of nine STR loci showed PIC (polymorphism information content, PIC) = or > 0.6378, H(heterozygosity, H) = or > 0.6500, DP (discrimination power, DP) = or > 0.8216, PPE (probabilities of paternity exculation, PPE) = or > 0.4903. The result indicated that there was a significant difference between Dongxiang ethnic group and the white and the black. There was no significant difference in Han nationality.These result filled the Dongxiang ethnic group-a specific group of Chinese into the genetic database and played an important role in Chinese population genetic study and forensic medicine application.
