The current Colombian population is the result of genetic admixture among Native Americans, Europeans and Africans. In this work, a sample of 121 non-related individuals from two Native American groups is analysed.

The  studied groups belong to communities that have been less subjected to admixture with non-Natives. The Barí, known as “Motilones”, are a native group that inhabits the Serranía del Perija, Norte de Santander. They still speak their original Chibchan language, Barí-ara.

We also studied a sample of natives from Guainía, composed of different groups that migrated from the Amazonia and Orinoquian regions, including the Desana, Curripaco, Puinave, Cubeo, Guaunano and Tucano, all belonging to Tucano and Arawak linguistic groups.

This study  determined genotypic and allelic frequencies for 46 ancestry informative InDels and estimated Native American, European and African admixture proportions. The results showed a very low European and African admixture in the Barí and Guainia native groups.
