The sero-anthropology of the Rhodesian Lemba

122 Rhodesian Lemba were blood grouped to establish whether there was any serological evidence to support their claim to be immigrants into central and southern Africa; and whether their endogamous practices had resulted in blood group frequencies different from those of their present neighbours. Our results are typical of those found in central Africa, and show no similarity to the blood group frequencies of populations outside sub-Saharan Africa.
