Some genetic erythrocyte polymorphisms in the Mbugu and other populations of the Central African Republic with an analysis of genetic distances.

Phenotype and gene frequencies of four blood group polymorphisms (ABO, MNSs, Rhesus, and Duffy) as well as hemoglobin types of four populations of the Republic of Central Africa are reported. All these polymorphisms are in Hardy-Weinberg equilibrium. Regarding the four blood group polymorphisms mentioned above the genetic distances according to NEI have been computed for fifteen populations of the Central-Eastern and Central-Western areas of Africa, including the four own samples. The results of these analyses are discussed.
