In the province of Buenos Aires, with a population of over 15 million inhabitants, aboriginal people currently account for 0.36%. Since the mid-40s, aborigines and their descendants, as well as European and Latin American immigrants, [comma] settled in the major urban areas, such as Buenos Aires city and its suburbs, fueled by industrial, agricultural and livestock activities. In order to evaluate the contribution of the various ethnic groups to the genetic make-up of the current population of Buenos Aires province, we analyzed uni- and biparental inheritance markers (mitochondrial DNA: control region and coding region SNPs, Y chromosome: SNPs and SNPs located on autosomal chromosomes). The results allow interpreting the processes of migration and mixing of cultures that co-participated in the present genetic constitution of the province that accounts for 52% of the total population of Argentina. Findings suggest a clear effect of ethnic displacement considering that at present, 20 generations after the first contact; it is not possible to detect individuals maintaining the genetic make-up of the pre-Hispanic populations of America.Downloads
