Determination of the Frequencies of ABO and Rhesus Phenotypes in Alshokria ethnic Group

Abstract

One hundred blood samples were collected in EDTA universal container form unrelated individuals in Alshokria ethnic group in all parts of Sudan during the period form 1/4/2005 – to 1/7/2005 . The ABO and Rh phenotypes performed immediately for each sample. The frequencies of ABO and Rh phenotypes were analyzed by using of the SPSS programme . Blood group O was found to be the most frequent 64% , the frequency of group A was 22% . For group B was 11% and for group AB was 3% . In Rhesus blood group system the frequency of Rh antigens D positive was 96%,C positive was 32%,c positive was 91%,E positive was 16% and e positive was 99%.The arranged phenotype frequencies of each individual was measured and it found that the most common phenotype cDe was 54% and Cce and cDE were very rare only was 1% for each. The correlations of Rh antigens were analyzed and it found that negative significance correlation between C and c and between E and e, but no significance correlations between C and D antigens.
