title: South African Negroes: isoenzyme polymorphisms (GPT, PGM1, PGM2, AcP, AK, and ADA) and tentative genetic distances.
abstract: Data on the genetic polymorphisms of the isoenzyme markers GPT, PGM1, PGM2, AcP, AK and ADA are presented for 7 ethnically defined Negro sub-samples (total n = 847-973, depending on the genetic marker concerned) from South Africa. The results are discussed in terms of previous findings, of the anthropogenetic interrelatedness of the populations concerned and of the factors assumed to have an influence on the distribution of the particular genetic markers. The entire data is subjected to the computation of "genetic distances" using several of the formulae available for this purpose. Some tentative conclusions on these results as well as on the formulae applied are drawn.
