Haplotype diversity and phylogenetic relationship analysis of Chinese Yulin Han population using 59 Y-STR loci of two novel Y-STR typing systems.

To investigate the genetic polymorphisms of 59 Y-chromosomal short tandem repeat (Y-STR) loci in the Yulin Han population, 229 unrelated healthy male individuals were analyzed using AGCU Y37 kit and AGCU Y-SUPP Plus kit. A total of 227 different haplotypes were obtained at the 59 Y-STR loci. Among them, 225 haplotypes were unique and 2 haplotypes occurred twice. The overall haplotypic diversity and discrimination capacity were 0.9999 and 0.9913, respectively. The phylogenetic relationships between the studied Yulin Han population and 17 previously reported reference populations were evaluated via multidimensional scaling and Neighbor-Joining analyses based on the haplotypic frequencies of 'YHRD Maximal Loci'. Phylogenetic analysis revealed that Yulin Han population was closely related to Chinese Han and Hunan Yao populations. These results demonstrated that the 59 Y-STR loci were useful for forensic applications and population genetic studies. Copyright © 2021. Published by Elsevier B.V.
