Blood group, protein, and red cell enzyme polymorphisms of the Hadza of Tanzania.

Three subpopulations of the Hadza were examined for the following antigens and proteins including enzymes A1ABH, MNS Henshaw, CcCwDDuEeVCe, Lua, KJsa, Fy1Fy2, JkaJkb, Dia, Wra, haemoglobin, haptoglobin, transferrin, acid phosphatase, glucose-6-phosphate dehydrogenase, 6-phosphogluconate dehydrogenase, phosphoglucomutase, adenylate kinase, lactate dehydrogenase, and malate dehydrogenase. The results are discussed in relation to other African populations including the Sandawe, Nyaturu, Pygmies, San, and Khoikhoi.

Colour-blindness and sensitivity to PTC in Hadza.

211 Hadza (Tanzania) males, including members of both western and eastern groups, were tested for red-green colour blindness with the Ishihara non-numeral plates. Three closely related individuals were considered to be protanopes. It is possible that they received the gene from an Isanzu ancestor. 118 individuals (both sexes) were tested for taste-deficiency to PTC using a single solution and a sorting test. 22% of the males and 27% of the females were considered to be non-tasters. Since this appeared to be a high figure for an African population a sample of 53 eastern Hadza males was later tested using solutions 1, 3, 5, 7, 9, 11, 13. A conservative interpretation of the threshold distribution gave an estimate of 43% non-tasters. Corrections were applied for the inclusion of close relatives in the samples. The results are discussed in relation to other African data.

Protein polymorphism in the Hanuman langur (Presbytis entellus).

26 specimens of Presbytis entellus were examined for a variety of blood proteins. In contrast to previous studies of other species of leaf monkeys, our P.entellus sample proved to be very heterogeneous. Polymorphisms were found in the third component of complement, group-specific component, glycine-rich beta-glycoprotein, alpha1-antitrypsin, phosphoglucomutase, 6-phosphogluconate dehydrogenase, adenylate kinase, superoxide dismutase, malate dehydrogenase, and phosphohexose isomerase. Variable band strengths that might represent polymorphism were found in acid phosphatase and lactate dehydrogenase. Further analyses of the P. cristatus sample studied by Barnicot and Hewett-Emmett failed to disclose variation. The interpretation of blood protein variability in relation to sample collection and population structure is discussed.
