“…To evaluate the genetic composition and stratification of the Colombian population, several studies have been performed using different types of ancestry and forensic markers in different populations throughout the country (Alonso Morales et al, 2018; Alonso & Usaquén, 2012; Ansari‐Pour et al, 2016; Bedoya et al, 2006; Bortolini, Salzano, & Thomas, 2003; Carvajal‐Carmona et al, 2000; Garavito et al, 2015; Ibarra et al, 2014; Martínez et al, 2017; Mesa et al, 2000; Noguera et al, 2014; Ossa et al, 2015, 2016; Rodas, Gelvez, & Keyeux, 2013; Rojas et al, 2010; Rojas, Roa, Briceño, Guaneme, & Gómez, 2011; Urbano, Portilla, Builes, Gusmão, & Sierra‐Torres, 2016; Xavier et al, 2015; Yunis, Acevedo, Campo, & Yunis, 2013). These studies showed that urban populations have high levels of non‐native admixture, and Native American, African, and European ancestries vary across the country.…”

Colombia, located in the north of the South American subcontinent is a country of great interest for population genetic studies given its high ethnic and cultural diversity represented by the admixed population, 102 indigenous peoples and African descent populations. In this study, an analysis of the genetic structure and ancestry was performed based on 46 ancestry informative INDEL markers (AIM-INDELs) and considering the genealogical and demographic variables of 451 unrelated individuals belonging to nine Native American, two African American, and four multiple ancestry populations. Measures of genetic diversity, ancestry components, and genetic substructure were analyzed to build a population model typical of the northernmost part of the South American continent. The model suggests three types of populations: Native American, African American, and multiple ancestry. The results support hypotheses posed by other authors about issues like the peopling of South America and the existence of two types of Native American ancestry. This last finding could be crucial for future research on the peopling of Colombia and South America in that a single origin of all indigenous communities should not be assumed. It then would be necessary to consider other events that could explain their genetic variability and complexity throughout the continent.

“…Analysis was carried out using the "Use Population Information" option, and allele frequencies were correlated and updated using only individuals with POPFLAG = 1. A gradient map based on the proportions of European ancestry in admixed South American populations [14,24,25,[27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43] was designed in the Surfer software v.16.0.330 (Golden Software, LLC, Golden, CO, USA), using the Kriging method for interpolating frequency values.…”

Immigrants from diverse origins have arrived in Paraguay and produced important demographic changes in a territory initially inhabited by indigenous Guarani. Few studies have been performed to estimate the proportion of Native ancestry that is still preserved in Paraguay and the role of females and males in admixture processes. Therefore, 548 individuals from eastern Paraguay were genotyped for three marker sets: mtDNA, Y-SNPs and autosomal AIM-InDels. A genetic homogeneity was found between departments for each set of markers, supported by the demographic data collected, which showed that only 43% of the individuals have the same birthplace as their parents. The results show a sex-biased intermarriage, with higher maternal than paternal Native American ancestry. Within the native mtDNA lineages in Paraguay (87.2% of the total), most haplogroups have a broad distribution across the subcontinent, and only few are concentrated around the Paraná River basin. The frequency distribution of the European paternal lineages in Paraguay (92.2% of the total) showed a major contribution from the Iberian region. In addition to the remaining legacy of the colonial period, the joint analysis of the different types of markers included in this study revealed the impact of post-war migrations on the current genetic background of Paraguay.
