Gm allotypes and racial admixture in two Brazilian populations.

Abstract:

:The Gm types of 515 inhabitants of Belém and 395 inhabitants of Porto Alegre, Brazil were studied in an attempt to quantitatively estimate ethnic parental contributions. The people from Belém can be characterized as 24% black, 22% Indian, and 54% Caucasian. The Porto Alegre blacks seem to have inherited as much as 53% of their genes from Caucasian ancestors, while the whites living there have inherited 8% of their genes from African ancestors. The admixture values obtained for Belém are very similar if just the Gm system is considered or it plus seven other loci are considered, emphasizing the high efficiency of the Gm markers in such analyses.
