Gc types in one Indian group and one Mestizo Mexican group.
The distribution of Gc types was investigated in an Indian group residing in Cuetzalan, Puebla, and in a Mestizo group from Mexico City. Gc1 and Gc2 gene frequencies were 0.862 and 0.138 in Cuetzalan, and 0.858 and 0.142 in Mexico City. These figures are similar to those obtained by other authors in one Northeastern Mexican City. A literature review showed that there appears to be a pattern of high Gc2 frequency in most Brazilian Indians (above 0.3) in contrast to a low frequency (below 0.2) in most other Amerindian groups studied.
