[Polymorphism analysis of 11 Y-STR loci in Manchu population and genetic relationships with 16 populations].
To investigate the genetic polymorphisms of 11 Y-chromosomal short tandem repeats(STR) loci in Manchu population, and to evaluate their forensic application values and genetic relationships with 16 other populations of China, 11 Y-STR loci in 203 unrelated Manchu individuals in Liaoning were amplified with PowerPlex Y System, and the PCR products were analyzed by 310 Genetic Analyzer. Cluster analysis and phylogenic trees were applied to show the genetic distance among the populations. As a result, a total of 189 haplotypes were identified and the overall haplotypes diversity for the 11 Y-STR loci was 0.9991. The gene diversity values (GD) for each locus ranged from 0.4594 (DYS391) to 0.9258 (DYS385a/b). Comparing with 16 populations, genetic distance between Manchu and Northeast Han population was the smallest(0.0015), while genetic distance between Man and Uygur ethnic the largest(0.1485). The phylogenetic tree was similar to the results of clustering analysis. The genetic distribution of 11 Y-STR loci in Liaoning Manchu population showed favorable polymorphisms, and was thus suitable for forensic identification and paternity testing in local area. The study of genetic diversity among different populations is useful for the research of their origins, migrations and their relationships.
