Abstract

ROJAS, WINSTON et al. SURNAMES AND Y CHROMOSOME COANCESTRY IN NORTHWEST COLOMBIA: A USEFUL TOOL TO ESTABLISH MIGRATION BETWEEN POPULATIONS. Rev. colomb. antropol. [online]. 2012, vol.48, n.1, pp.49-79. ISSN 0486-6525.

Using Y chromosome genetic markers we studied the lineage composition and distribution in the most common surnames in 471 males from the municipality of Marinilla and its zone of influence, the municipality of Aranzazu (department of Caldas) and a group of samples from the general population of Medellin (Antioquia). Despite a variable rate of coancestry between surnames and Y-chromosome markers, we found a high similarity in the pattern of distribution of haplogroups/haplotypes/ surnames between Marinilla and its zone of influence and Aranzazu, reinforcing the historical migration between these two regions. This similarity would indicate that in both populations may be circulating common genetic variants linked to human diseases.

Keywords : surnames; Y chromosome; paternity.
