title: [Genetic polymorphism of fifteen short tandem repeat loci in Chinese Drungs].
abstract: OBJECTIVE
  To study the short tandem repeat (STR) polymorphism in Chinese Drungs (Tulungs).
  
  
  METHODS
  The genetic distributions of fifteen STR loci were investigated with the use of coamplification, genescan and genotype from 67 Drungs.
  
  
  RESULTS
  There were 144 STR alleles in Drung nationality, with their frequencies ranging from 0.0077 to 0.7846, heterozygosity(H) 0.3723-0.8639, discrimination power(DP) 0.5567-0.9548, probability of paternity exclusion(EPP) 0.2738-0.8358, polymorphism information content (PIC) 0.3461-0.8456  the accumulative DP 0.99999998 and EPP 0.99999894.
  
  
  CONCLUSIONS
  The results of this study on the STR polymorphism in Chinese Drungs could be used as a basis for the genetic structure of Chinese ethnic groups and also be of significant application in anthropology and forensic science.
