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 cit...

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. Actualmente en la provincia de Buenos Aires, con una población de más de 15 millones de habitantes, los pueblos aborígenes representan el 0,36%. Desde mediados de los ‘40, tanto los aborígenes y sus descendientes, como los inmigrantes europeos y latinoamericanos instalados en el interior del país fueron migrando tanto a la ciudad de Buenos Aires como a su conurbano, fenómeno fomentado por la actividad industrial y agrícola-ganadera. Con el objeto de evaluar el aporte de los distintos grupos étnicos a la composición genética de la población actual de la provincia de Buenos Aires (centrándonos en CABA y conurbarno), llevamos a cabo el análisis de marcadores genéticos de herencia uni y biparental (ADN mitocondrial: región de control y SNPs de región codificante, Cromosoma Y: SNPs y SNPs localizados en cromosomas autosómicos). Los resultados obtenidos permiten interpretar los procesos migratorios y de mestizaje que co-participaron en la constitución actual de la provincia, cuya población representa el 52% de la población total del país. De estos resultados surge un claro efecto de desplazamiento étnico ya que después de 20 generaciones del primer contacto no es posible detectar individuos que mantengan la estructura genética de las poblaciones originarias de América.
