The Wapishana are an Arawak speaking indigenous population residing in northern Brazil and along the border of southern Guyana. Historical records indicate the Wapishana have lived near neighboring indigenous populations and had over 200 years of contact with Europeans. It’s been hypothesized this has resulted in a high amount of admixture between the Wapishana and surrounding indigenous and nonindigenous groups. Previous Wapishana mitochondrial DNA (mtDNA) haplogroup frequencies (n = 12) determined by Merriwether et al. (1996) revealed the presence of the New World founding haplogroups B, C, and D with the absence of A. To further assess the genetic relationships of the Wapishana population, 258 maternally unrelated individuals were sequenced for Hypervariable Regions 1 and 2 residing within the D-loop of the Mitochondrial genome and 125 paternally unrelated Wapishana men were chosen for Y-chromosome analysis. The Wapishana were compared to other South American groups to assess maternal and paternal gene flow patterns.
