The result showed that the frequency of Rh positive was found to be (93.1%) and Rh negative was (6.99%). The Rh phenotypes in 87 Rh negative blood samples present in decreasing order of frequency were as follows: rr, r1r, r11r, r1r11, r1r1, r11r11, ry . The results of this study were compared with the results of other studies.
