Mitochondrial DNA Haplogroups Observed in Iraqi Population

Mitochondrial DNA hypervariable regions I and II of control region were sequenced from 100 random healthy unrelated individuals of three sequential generations belong to the Arab ethnic of Iraqi population. The aim of this study was to detection the mtDNA haplotypes and classifying it into mtDNA haplogroups will be useful in forensic genetics applications and determining the Iraqi population history. The sequence variation within D-loop control region were analyzed the composition of haplogroups that showed high frequency of haplogroups U, H, J, M, D, T and N (18 %, 14 %, 10 %, 9 %, 7 %, 7 % and 7 %, respectively, moderate frequency of haplogroups L and I was (4 %) and B, A, R and K (2 %), and low frequency of haplogroup pre-HV (1 %). This study was indicated lack of V, P, Y, X, O, Z, Q, G, E and C haplogroups.
