Abstract
Three hundred ninety‐three individuals from the Universidad Autonoma de Puebla and its University Hospital were studied to determine the distribution of ABO, MN, Rh‐Hr, Duffy, and Diego blood groups; red cell hemoglobin and glucose‐6‐phosphate dehydrogenase variants; and serum haptoglobins, albumins, and factor Bf types. With the results we estimated that the proportions of black, indian, and white genes are 10.7%, 56.3%, and 33.0%, respectively, in a trihybrid model. Reasons are given as to why the black ancestry may be artificially high, and it is pointed out that independent confirmation with other markers is needed before the figure can be accepted as a true value.
