title: [Genetic polymorphism of 10 STR loci on chromosome 9 and its forensic application in Chinese population].
abstract: OBJECTIVE
  To have a thorough knowledge of the genetic polymorphism of 10 short tandem repeats loci of chromosome 9 in Chinese population and its application in forensic science.
  
  
  METHODS
  The 9 STR tetrameric loci and one trimeric tandem repeat locus were chosen from Genome Databank. Eighty-three EDTA-blood samples were collected from the unrelated family in Baiyin city, Gansu province. DNA was extracted by Chelex method and amplified by the polymerase chain reaction(PCR). The PCR products were analyzed by PAGE electrophoresis.
  
  
  RESULTS
  The polymorphisms of all 10 STR loci have been obtained in Chinese Han population. The 10 STR loci follow the Mendel ns law.
  
  
  CONCLUSIONS
  The data of all 10 STR loci is beneficial to understanding the population genetics of them in Chinese Han population.
