title: Gene frequencies and racial intermixture in a Mestizo population from Mexico City.
abstract: Blood specimens from a sample (of some 460 subjects) from the Mestizo population in Mexico City were tested for haptoglobin, transferrin, glucose-6-phosphate dehydrogenase, acid phosphatase and haemoglobin types and blood groups. Gene frequencies for these characters were estimated. From the data on O, M, N, S, R degrees, r, Pc frequencies, the amount of admixture was calculated. In the Mestizo population studied the major contribution comes from European sources and the secondary contributions from Mexican Indians; the contribution from African sources is minimal.
