ABSTRACT
<p><b>OBJECTIVE</b>To study the polymorphisms of DYS287 and DYS440 in Zhejiang She population.</p><p><b>METHODS</b>Detection of DYS287 and DYS440 polymorphisms was performed in 100 She individuals by using polymerase chain reaction amplification and 2% agarose gel electrophoresis.</p><p><b>RESULTS</b>With 150 bp product in all She individuals, YAP(+) was absent. DYS440*3 was present in 10 She individuals (10%); DYS440*4 was present in the other 90 She individuals(90%).</p><p><b>CONCLUSION</b>The polymorphisms of DYS287 and DYS440 in Zhejiang She population were different from those in the other populations that belong to Sino-Tibetan Language Family. So both DYS440 and DYS287 are important and stable genetic markers, they can provide reliable evidence in human evolution study.</p>
