Distribution of four STR loci's haplotypes in Guangdong Han Population / 中国法医学杂志

ABSTRACT

To investigate haplotype distribution of the Y-chromosome STRs (DYS19, DYS390 and DYS389 locus) in Han population in Guangdong area. The STRs were typed by poplymerase chain reaction followed by discontinuous PAGE system. Among 130 unrelated males, 81 different haplotypes were observed, 52 out of them were found only one time. The haplotype genetic diversity, discrimination power and non-father exclusion chance are 0. 9989, 0. 9824, 0. 9824, respectively. The high informative haplotypes make these STRs useful for the forensic individual identification and paternity testing.
