“…Suffice it to empha size that the specimens of serum remained frozen (about -15 C) until they were thawed and sub-di vided for Ag typing at the Central Laboratory of the Blood Transfusion Service of the Swiss Red Cross in Berne. The sera were typed in duplicate, using the passive haemagglutination inhibition method 12,3], Whereas the majority of the Ne groid specimens was tested for the Ag(x) and Ag(y) specificities only, the sample of Indian as well as a sub-sample of Negroid serum specimens was tested for (he near-complete panel of the nine common Ag specificities, i.e..

Two population samples from South Africa, i. e. 555 Bantu-speaking Negroids and 75 Indians, were tested for selected immunogenetic specificities comprising the Ag polymorphism. Within the Negroid sample a new Ag phenotype (i. e. the 49th) was discovered. Interpopulational comparisons involving the present two, as well as three previously studied samples, reveal characteristic differences in regard to the frequency distribution of Ag phenotypes, to the Ag allele frequencies and to the occurrence of Ag haplotypes. These results are discussed. All the data could be interpreted satisfactorily in terms of the genetic model regarding the Ag system as postulated by Bütler and his co-workers.
