Two hundred eighty subjects comprising 112 Nuba and 168 Hawazma of the Sudan were tested for the distribution of hemoglobins, eight red cell enzymes, and four serum proteins. The Nuba, the indigenous negroid tribe, had no Hb S , Hb O‐Arab , or Gd B(Khartoum) compared to the Hawazme tribe of Negro‐Arab descent. The gene frequencies of the above polymorphic systems in the latter were as follows: Hb S , 0.13; Hb O‐Arab , 0.01; Gd B(Khartoum) , 0.03. The frequency of Gd A was higher in the Hawazma than in the Nuba. A high frequency of glucose 6‐phosphate dehydrogenase (G6PD) deficiency and Hp O was present in both the tribes. Essentially similar gene frequencies of Hp 1 , Tf D , PGD C , p C , and PGM 1 were observed in both Nuba and Hawazma. The average heterozygosity at five polymorphic loci was the same (0.23) in both the tribes. The above results agree with the social practice whereby people of mixed Hawazma and Nuba descent are considered members of the Hawazma tribe and confirm that racial admixture between the two groups can be seen as a process of gene flow from the Nuba to the Hawazma, even though the Nuba are the indigenous group, while the Hawazma are the new settlers.
