- 10 Downloads
The Y-chromosome Alu polymorphism was studied in 10 populations in China. The Alu insertion is present in 54/571 individuals (9%). Among 10 populations, the frequency of YAP element is quite high (49%) in the Tibetans and at moderate or low levels (15%-4%) in the Yi, Hui and Uygur. The Alu insertion is absent in the Han in Guangdong and Shaanxi, and in the Manchu and Zhuang, while a single Tujia individual and a single Yao individual are found to have the Alu insertion.
