“…Populations from the Jujuy highlands showed almost 100% Amerindian ancestry, whereas the gene pool of the lowest population nuclei featured European and, to a lesser extent, African contributions (Dipierri et al, ; Martinez‐Sarasola, ). Along these lines, some previous investigations on Y‐chromosome haplogroups have confirmed the presence of a certain proportion of haplotypes of European origin in Jujuy lowland subpopulations (Altuna et al, ; Ramallo et al, ).…”

“…The study of NRY markers highlighted a high Native American component in the paternal lineages, as can be inferred from the genetic affinity of Jujuy subpopulations with other South Amerindian samples from surrounding communities (see Figure ). Predominance of the Native American genetic background in Jujuy has been reported in previous works based on a variety of genetic markers: autosomal loci, such as immunoglobulin allotypes, serum polymorphisms (Dipierri et al, ), polymorphic Alu insertions (Gómez‐Pérez et al, ), STRs of human chromosome 6 (Gómez‐Pérez et al, ), and uniparentally inherited markers, such as Y‐STRs (Bianchi et al, ), Y‐chromosome haplogroups (Altuna et al, ; Ramallo et al, ), and mitochondrial DNA lineages (Cardoso et al, ). All these findings contribute pieces of evidence for the high degree of conservation of the Amerindian gene pool in the zone (Bailliet et al, ; Cardoso et al, ; Gómez‐Pérez et al, ).…”

“…In accordance with the cited studies, previous research by these authors have detected a major Native American contribution to the current gene pool of Jujuy populations, through the analysis of both autosomal markers (Gómez‐Pérez et al, ) and female genetic lineages, that is, mtDNA haplogroups (Cardoso et al, ). In regard to the Y‐chromosome, allochthonous haplotypes have been identified in some localities of Jujuy although with lower frequencies than in the rest of the Argentina provinces (Bianchi et al, ; Bianchi, Bailliet, Bravi, Pena, & Rothhammer, ; Diaz‐Lacava, Walier, Penacino, Wienker, & Baur, ; Ramallo et al, ).…”

Objectives: This study aimed to explore the diversity of paternal lineages in Jujuy province (Argentina) by analyzing Y chromosome markers. Furthermore, we examined among-population genetic variability based both on paternally (NRY haplotypes) and maternally (mtDNA haplogroups) inherited markers. We sought to evaluate the impact of sex-biased gene flow on genetic background in Jujuy, and contribute data on the microevolutionary forces acting in this zone. Methods: DNA from 149 males from five Jujuy regions were analyzed for 12 nonrecombining Y (NRY) markers. Genetic heterogeneity among Jujuy regions was evaluated through population differentiation tests. To identify potential genetic boundaries in Jujuy, analysis of molecular variance (AMOVA) and the Monmonier's algorithm implemented in the Barrier v2.2 software were employed. Results: A clear divergence between Jujuy highlands and lowlands for NRY haplotypes was found. A marked discrepancy between genetic structuring for paternal lineages and the lack of geographical pattern for mitogenomes was confirmed by all statistical analyses. Conclusions: Genetic structuring of paternal lineages is most likely caused by admixture processes that have occurred since colonial times in the Jujuy lowlands.Immigrants were predominantly male that settled in the lower altitude zones, due to the steep orography of the region. Input of allochthonous male lineages because of gene flow toward the lowlands would have increased diversity of NRY markers, thus compensating for drift effects. Likewise, limited input of allochthonous mitogenomes would have promoted genetic drift, a key factor in the shaping of diversity of maternal lineages across Jujuy subpopulations, irrespective of altitude.

“…El trabajo ininterrumpido desde entonces ha permitido obtener una imagen clara sobre la variabilidad de los linajes paternos presentes a lo largo de parte de la geografía argentina, dejando en claro que, salvo algunas particularidades regionales, los ancestros masculinos de las poblaciones mestizas presentes son primordialmente de origen euroasiáticos, mientras que la porción minoritaria está constituida por linajes nativos y africanos. La fracción alóctona, en la mayoría de los casos, se encuentra constituida por el haplogrupo R, seguido por el macro-haplogrupo F, en tercer lugar por los haplogrupos DE, y en menor frecuencia por K (Altuna et al, 2009;Bailliet et al, 2011;Corach et al, 2010;García, Pauro, Bailliet, Bravi y Demarchi, 2018;Parolin et al, 2012;Ramallo et al, 2009). Mientras que la porción nativa se halla representada en gran proporción por el clado pan-americano Q1b1a1a (Q-M3) (Bailliet et al, 2011).…”

Se analiza el origen continental de los haplogrupos del cromosoma Y en poblaciones de Santiago del Estero y San Miguel de Tucumán con el fin de ampliar el mapa filogeográfico de los linajes paternos argentinos. Se recolectaron 283 muestras de sangre con encuestas genealógicas a donantes voluntarios de sexo masculino en centros de salud públicos y privados de ambas localidades. Mediante PCR alelo-específica se tipificaron 18 marcadores bialélicos de la región no recombinante del cromosoma Y de presencia ampliamente confirmada en Argentina. El 89% de los linajes fueron de origen euroasiático, el 7% americano y el 4% fueron identificados como de posible ascendencia africana y/o del sudoeste asiático, debido a su asignación al linaje E1b1a1. Las frecuencias de haplogrupos de las poblaciones muestreadas fueron semejantes a las de poblaciones de las regiones Pampeana, Cuyo y Noreste. La muestra procedente del centro privado de Tucumán presentó en sus haplogrupos alóctonos frecuencias similares a las reportadas para Europa y Medio Oriente, corroborando que los tres contingentes migratorios que han aportado mayor número de inmigrantes en San Miguel de Tucumán: españoles, italianos y árabes, han dejado su huella en el acervo genético de sus poblaciones actuales. El patrón de distribución de los haplogrupos nativo americanos del cromosoma Y no difiere sustancialmente del detectado en el noroeste y en otras poblaciones argentinas y el mismo es congruente con la información arqueológica, etnohistórica y censal de Santiago del Estero y San Miguel de Tucumán.
