    The Chilean genetics

    Chile is one of the most mixed countries on latinoamerica. The insular caracteristics of the land, enclosed by deserts in the north, mountains on the east and sea on the south and west contributed to create very homogenous distributions of admixture on the population.

    The people of Chile began their process of mixing during the Spanish Conquest, and quickly the local indigenous population began to be replaced by the mestizo component, as early as the mid-sixteenth century in the center and north of Chile. The south, on the other hand, remained relatively but not completely, oblivious to the mixture due to the Arauco War and the combative attitude of the Araucanian tribes.

    In the center, the mix was mainly with Picunche Tribes and with the colonists of the Incan Empire, who were there since the 15th century. In the north, the Diaguitas and Atacameņos peoples contributed to the miscegenation.
    The African component, clearly lower in Chile than in other Latin American countries, was greater at one time but began to fade over time, and although it has a very low presence in the central and southern areas, it is more prevalent in the north of the country.

    At the end of the 18th century, French components began to arrive, then, coinciding with the Wars of Independence, merchants and English soldiers contributed to the Chilean genetic well. Already at the beginning of the 20th century, Germans, Italians, Croats, Palestinians, among others, arrived. However, the main sources of the Chilean mix are still Amerindian and Spanish.


    In the year 2019 a study by the University of Chile determined that 80% of the Chilean population has haplogroup Y of the old world, and X amerindian, confirming that mestizaje in Chile occurred mainly between European men and women of the continent.

    "We find CHL ancestry percentages being 42.38% NAT, 55.16% EUR and 2.44% AFR (using LAMP-LD) and 43.22% NAT, 54.38% EUR and 2.40% AFR (using RFMix), which are consistent with previous studies"

    Scientific analyzes show genetic continuity of a thousand years in the Patagonia settlement

    "Researchers of the Human Genetics program made the first study of complete genomes in the country, with ancient samples of fisher/gatherer hunters from Patagonia. Funded by Conicyt, the project was led by Chilean scientists in collaboration with the universities of Stanford and Copenhagen. The study was able to establish the genetic affinity of contemporary and ancestral communities, despite the rapid decline in native populations after the arrival of European settlers, which in some cases ended in genocide".
