title: S--s--U-- phenotype in the coloured population of Cape Town: problems encountered in paternity tests.
abstract: Two Cape Coloured persons of mixed White, Khoikhoi, Malay, Black parentage in Cape Town whole red cells were found to be S--s--U-- establish that the rare Su allele is present in this population group. The most likely source of the Su allele in them is the non-indigenous Black slaves who were brought to the Cape in the early years of White settlement there. In two paternity suits involving Cape Coloured persons, maternal and paternal exclusions were present unless the inheritance of an MSu or an NSu chromosome was postulated, and MS, NS and Ns chromosomes were seen to accompany He+ alleles in them.
