Native American mitochondrial lineages in admixed populations from Chile: Detecting recent migrations during post-Columbian times using geographically restricted lineages.

Objectives: To analyze the mitochondrial diversity in three admixed populations and evaluate the historical migration effect of native southern population movement to Santiago (capital of Chile). The intensity of migration was quantified using three mitochondrial lineages restricted to South-Central native groups.

Methods: D-loop sequences were genotyped in 550 unrelated individuals from San Felipe-Los Andes (n = 108), Santiago (n = 217), and Concepción (n = 225).

An approach on the migratory processes in the north of Chile based on Y chromosome analysis.

Objectives: Northern Chile is an area characterized by a complex cultural and demographic trajectory. During the last few centuries, this complex trajectory has become the destination of intra- and intercontinental migratory waves. In this study, we analyzed the Y chromosome to evaluate how migratory and admixture patterns have affected the genetic composition of the populations in northern Chile compared with other populations of the country.

Ancestry and admixture of a southernmost Chilean population: The reflection of a migratory history.

Objectives: Punta Arenas is a Chilean city situated on ancestral Aönikenk territory. The city was founded by 19th- and 20th-century colonists from Chile (Chiloé) and Europe (Croatia). This work uses uniparental and ancestry-informative markers (AIMs) to explore the effects of historic migratory and admixture patterns on the current genetic composition of Punta Arenas.
