DI FABIO ROCCA, Francisco et al. Population history and anthropogenetic analysis of the city of Salta. Andes [online]. 2016, vol.27, n.2, pp.00-00. ISSN 1668-8090.

In the present study the genetic composition of Salta capital city was estimated in a population sample. A total of 223 non related blood-donors from the Centro Privado de Hemoterapia were included, who provided written informed consent and genealogical information. Twelve autosomal markers, GM allotypes, mtDNA and Y-chromosome continental origin were analysed; genetic admixture was estimated employing the ADMIX program. Autosomal markers show the presence of 50,02% for the Amerindian component, 46,29% for the European and 3,51% for the African component. Amerindians mitochondrial haplogroups represented a 93,75%, while the Europeans haplogroups represented a 3,85% and the Africans a 2,40%; 17,1% of males analysed exhibited the aboriginal variant Q*M3. The data were compared to those obtained previously in other cities, and the genetic admixture of Salta showed the highest values of Amerindian and African component. The intraregional immigration is much more remarkable than interregional or foreign immigration. These studies reinforce the idea that the Argentine population should not be considered as a homogeneus totality but variability must be taken into account.
