Abstract: | In this study, we investigated the genetic characteristics of 25 Y-chromosomal short tandem repeat loci in 305 unrelated Chinese Han male individuals from Liaoning Province, using AmpFISTR® Yfiler® Plus amplification kit. A total of 293 different haplotypes were observed at the 25 Y-STR loci; among them, 281 were unique and 12 were occurred twice. The overall haplotype diversity was 0.9997 and the discrimination capacity was 0.9607. The gene diversity values ranged from 0.4525 (DYS391) to 0.9617 (DYS385). Population relationships between our data and other published populations were measured by Rst and visualized in two multi-dimensional scaling plots. The results showed that the 25 Y-STR loci in Liaoning Han population are valuable for forensic application and human genetics. |
