Forensic and phylogenetic analyses among three Yi populations in Southwest China with 27 Y chromosomal STR loci
We have analyzed the Y chromosome haplotypes of 510 non-related Yi males grouped in three Chinese provinces (Guizhou, Sichuan, and Yunnan) using the Yfiler® Plus Kit. A total of 484 haplotypes were detected, out of which 460 were unique. The observed haplotype diversity and discrimination capacity were 0.9998 and 0.9490, respectively. To investigate the genetic relationship of the studied population, multidimensional scaling (MDS) plot and neighbor-joining (NJ) tree phylogenetic analyses were constructed which demonstrated that the Y chromosome lineage among the Yi ethnicity was different.
