(Concluded from p. 170, 10 March 1951) The distribution of the blood groups ABO, MN, P and Rh in the South African Bantu has been studied. The calculated frequencies of the genes demonstrate that this race is genetically homogeneous and possesses a distribution of genes which is unique among the peoples of the world. The theories of heredity of the blood groups are discussed in the light of the findings, particularly the genetics of the Rh system. Evidence is adduced in favour of the theory of multiple allelomorphs for composite Rh genes at a single locus on the chromosome.
