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).
