Abstract:

Objective To study the genetic relationship of the Y chromosomal short tandem repeat gene loci in Lanzhou Han population and other 25 populations. Methods The frequency of alleles of Y-STRloci was obtained from a sample of 500 unrelated individuals living in Lanzhou City, and other 25 populations in different areas collected from the published data were used to calculate the genetic similarity coefficient and genetic distance. Phylogenetic trees based on the genetic distance were established. Results Populations of Lanzhou, Beijing, Shanxi and Inner Mongolia were in an identical cluster. Compared with minorities, the genetic distance between Lanzhou Han population and Inner Mongolia Mongolian population was dramatically smaller from other subpopulations. The populations in Malays and Indians were far from the other groups. Conclusion The Y-STR gene frequency distribution in 26 populations has identified differentiation in race, clime and evolution, and it is basically identical with the classification of human races which is similar to or according with other molecular anthropology research conclusions.
