Abstract:
In this study, 22 Y-specific STR loci (DYS19, DYS389I/II, DYS390, DYS391, DYS392, DYS393, DYS385, DYS437, DYS438, DYS439, DYS461, DYS481, DYS504, DYS505, DYS508, DYS533, DYS576, DYS588, DYS607, DYS634, and DYS643) were analyzed in 216 unrelated male individuals from southeast China (Chaoshan area) by three multiplex PCR systems. The haplotype diversity using the classical set of Y-STRs (DYS19, DYS389I/II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, DYS439, and DYS385; PowerPlexY Systems) was 0.9908. For the same population sample, the haplotype diversity using the new sets of 11 novel Y-STRs (DYS461, DYS481, DYS504, DYS505, DYS508, DYS533, DYS576, DYS588, DYS607, DYS634, and DYS643; multiplex I and II) was 0.9917. By combining the allelic states of the 22 Y-STR loci we could construct highly informative haplotypes that allowed the discrimination of 99.1% (214 out of 216) of the samples tested and the overall haplotype diversity of 0.9999. These results, including the haplotype data at 22 Y-STR loci in the present study, provide useful information for forensic practice in the Chaoshan population in southeast China.
