Abstract

We reported the multiplex-PCR-based genotyping method for 7 Y-STR loci, including DYS456, DYS464a/b/c/d, DYS527a/b labeled with FAM (blue) and DYS531, DYS709, DYS448, DYS522 labeled with JOE (green). We investigated the haplotype distribution of these 7 Y-STR loci among 151 unrelated Han males in the Guangdong Province and 106 unrelated males in the Henan Province, and evaluated this method for forensic practice. The results showed that this method could successfully determine the genotypes using as little as 0.02 ng genomic DNA, and the male's Y-STR genotypes could be detected in a DNA mixture in which the ratio of male/female components was 1:150 (160 ng in total amount of DNA template). There were 150 and 105 haplotypes found of these 7 Y-STR loci in these two Chinese populations, out of them 149 and 104 haplotypes appeared only once, respectively. The haplotype diversity in the two populations were 0.999912 and 0.999820, respectively. The distribution variation of the 7 Y-STR haplotypes between Guangdong and Henan Chinese populations was statistically significant (P<0.001). Thus, the fluorescein-labeled multiplex-PCR genotyping of 7 Y-STR loci is a valuable tool for forensic medicine practice and for human anthropology study.
