A 2014 autosomal DNA study, which analysed data from 1594 samples from all of the Brazilian regions, found that Brazilians show widespread European ancestry with the highest levels being observed in the south. African ancestry is also widespread (except for the south) and reaches its highest values in the East of the country. Native American ancestry is highest in the north-west (Amazonia). In conclusion, European ancestry accounts for 82% of the heritage of the population, followed by the African (9%) and the Native American (9%).
