Resumen:
The aim of this work was to analyze the origin of the Y-chromosome haplotypes in a sample from Buenos Aires Metropolitan Area (BAMA), and to compare these results with data obtained at mitochondrial level. In order to reach this objective, 17 Y-STRs were determined from 85 unrelated blood donors. A total of 85 unique haplotypes were observed. The haplotype diversity was 1.000+/-0.0018, and the average genetic diversity 0.680+/-0.095. The paternal lineages present a genetic homogeneity of European roots (93%), coming mainly from Italy and Spain. Amerindian paternal contribution associated to sub-haplogroup Q1a3a was relatively low (6%). The low proportion of Amerindian haplotypes and the high number of maternal lineages (44%) from the same sample reveals that there has been a differential input by gender in the history of this population. A single profile was E1b1a, which is predominant in sub-Saharan Africa. These data, together with the historical and demographic information, allows us to state that the small Amerindian and sub-Saharan contribution observed in the sample from BAMA, would be the result of recent migrations, initiated in the middle of twentieth century, mainly from the north of Argentina and bordering countries of high native composition and, to a less extent, African origin.
