title: [Investigation of Y chromosome and polymorphism of 5 Chinese ethnic groups in Yunnan Province, China].
abstract: OBJECTIVE
  To investigate the polymorphism of DYS287 in the Han, Dai, Lahu, Wa and Tibetan groups living in Yunnan Province, China.
  
  
  METHODS
  YAP element was detected by PCR amplification and agarose gel electrophoresis.
  
  
  RESULTS
  With 150bp product in all Han,Dai, Lahu and Wa individuals, YAP element is absent. In 11 Tibetan individuals out of 30, YAP element is present and the PCR product is 455bp.
  
  
  CONCLUSIONS
  As an important and stable genetic marker, DYS287 can provide reliable evidence in evolution study.
