DETERMINATION OF ABO &RHESUS PHENOTYPES AND THEIR FREQUENCIES IN HALFAWEEN ETHNIC GROUP

Abstract

The ABO and Rh phenotypes and their frequencies were determined on 100 subjects from Halfaween tribe in Sudan, they were of no relationship. The ABO phenotypes was appeared to follow the formula O > A> B > AB. Blood group O was found to be the most frequent (44%). The incidence of blood group A was (31%), for group B (22%) and for group AB (3%). In the Rhesus blood group system antigens, the incidence of Rh (D) antigen positive was (95%), the incidence of C antigen positive was (69%), for c antigen positive (78%), for E antigen positive (20%) and for e antigen positive (90%). In contrast the most frequent Rh phenotype was found CcDe (32%), for CDe phenotype (21%), for cDe phenotype (21%), for cDEe phenotype (7%), for CcDEe phenotype (7%), for ce phenotype (3%), for Cce phenotype (3%), CcDE phenotype (2%), for CDE phenotype (2%) and for cDE phenotype (2%).
