Antecedentes y nuevos aportes en el estudio del cromosoma Y en poblaciones humanas sudamericanas
Advances in the knowledge of the human genome have also impacted in the comprehension of the specific region of the human Y-chromosome. In the last years, almost 600 bialelic polymorphisms (SNP) have been described, allowing a consistent phylogeny to be constructed based on them, and the normalizati...

| description |
Advances in the knowledge of the human genome have also impacted in the comprehension of the specific region of the human Y-chromosome. In the last years, almost 600 bialelic polymorphisms (SNP) have been described, allowing a consistent phylogeny to be constructed based on them, and the normalization of nomenclature. In the present work we have analyzed 940 samples from males of 10 aboriginal populations from Argentina, Chile and Paraguay; and 12 urban populations from Argentina. Nine SNP that characterize mayor clades of the phylogeny have been analyzed, enabling the recognition of the Q* and Q3 Native American haplogroups, and AB, DE, F, K, P y R foreigner haplogroups. Fst was 0.17, showing a high level of differentiation between populations. The MDS analysis showed a differentiation between aboriginal populations and urban, the stress was 0.0297 meaning a good adjustment. The self-identified aboriginals and Jujuy populations showed a high proportion of Y-chromosomes from Q3 haplogroups, the Paraguayan populations differentiated from the others due to their high proportion of Q* haplogroups. The urban populations were characterized by the foreign haplogroups entering in those populations by migrations from Europe and other regions. |
