Estudio de la estructura genética de una comunidad nahua del centro de Veracruz

Abstract

With the aim to establish the bianthropological diversity in the central region of the state of Veracruz, several biochemical and molecular genetic markers in the Ixhuatlancillo population were analyzed and compared with the findings obtained in a Mexican mestizo population. The genotypic distribution of the ABO and RH blood groups, and the alelic frequencies of LDLR, GYPA, HBGG, D7S8, GC y DQ Alfa-1(HLA) genes were established in both populations. The results indicate a high frequency of indigenous genes in both populations, but important genotypic differences between the two populations were revealed by the molecular polymorphisms. The Ixhuatlancillo nahua population was more homogeneous an showed a lower number of heterozygote in GYPA, HBGG and D7S8 genes, probably due to a selective pairing within the same ethnic origin. The mestizo population is more heterogeneous because it has been conformed by several different genetic contributions.
