D-- and Dc- gene complexes in the coloureds and blacks of Natal and the eastern Cape and blood group phenotype and gene frequency studies in the Natal coloured population.

Abstract excerpt

Following the detection of apparent exclusions in the Rh system in two Coloured (mixed race) families during paternity testing, a rare D-- gene complex was identified in one family and two examples of an unusual gene complex producing weak e and very weak or non-demonstrable f antigen in the other. The latter, which almost certainly belong to the heterogeneous collection known as Dc-, were found when the Rh...
