Estimation of Allele and Haplotype Frequencies for 17 YSTR Markers in the Diyala Arab Population

Abstract

In this study, 17 Y chromosome –Short tandem Repeat (Y-STR) sites were (DYS635, DYS437, DYS448, DYS456, DYS458). YGATA H4 DYS1919, DYS38911, DYS90, DYS391, DYS392, DYS393, DYS438, DYS439 and DYS385 a / b) were analyzed in 110members of the Diyala Arab population. According to measures of genetic diversity the highest diversity was observed at loci DYS385a/b= (0.933), DYS458=( 0.830) Low gene diversity (0.253). Therefore, these loci should be considered the most diverse and polymorphic for forensic testing that can be used to distinguish between male relatives. Genetic diversity values ranged from 0.253 to 0.933. The Diyala Arab populations is largely heterogeneous and a total of 78 different haplotypes were observed, there were 55 (0.009091) uniques haplotypes and 23 haplotype were shared between individuals. Haplotype diversity was 0.9990 and Discrimination capacity (DC) (0.705128).
