Y-chromosome STR-haplotype typing in El Salvador

Eight Y-chromosome STRs were investigated in a male population sample from El Salvador. Complete Y-chromosomal STRs haplotypes were obtained in 121 individuals, among which 107 different haplotypes were observed. The two most common haplotypes were shared by approximately 4% of the sample, while 100 haplotypes were unique. The gene diversity was 0.9883 and the discrimination capacity was 0.8926. The combined Y-chromosome STR polymorphisms provide a powerful discrimination tool for routine forensic applications.
