MTDNA control region analysis of North Brazilian population

MTDNA control region analysis of North Brazilian population

Abstract:

South America’s demographic complexity has been historically influenced by population interactions such as the European migration and African slavery trade, besides Native Americans groups previously settled in the territory. In Brazil colonization occurred alongside different historical events at the beginning of the 16th century which intensely contributed to the genetic admixture. This study targets to enlarge on the databases with matrilineal lineages of Brazilian populations. We analyzed the mtDNA control region of blood spots from 116 individuals belonging to the North region of the country. All samples were processed by direct amplification and sequenced with fluorescent dye terminators kit by capillary electrophoresis. The haplogroups were assigned using the EMPOP online platform. Our data revealed higher rates for the Native American ancestry (57.8%), followed by African (36.2%) and European (6.0%) proportions. Considering the lack of mitochondrial lineages data further studies should be conducted in order to fully elucidate anthropological and population genetic pattern across the country.
