English: African regions contributing to the populations of the Americas. (a) Left: proportion of W/WC Africa contributing to the mtDNA pools of North (N, USA), Central (C, Caribbean), and South (S, Brazil) America as reported by Salas et al. Right: the proportion of West/West-Central (W/WC), South-West/West-Central (SW/WC) Bantu and South-East (SE) Africa contributing to mtDNAs in comparative populations of America analyzed in this paper (“Stefflova”). The relative contributions of these large African regions agree with Salas et al., except for the Brazilian sample that displays significant input from SE Africa as well, which may have been included in WC portion by Salas et al. (b) Within-Africa mtDNA variation of admixed populations of Americas within the context of the colonial system. Maps are colored, depicting the relevant British (brown), French (light gray), Portuguese (blue), and Spanish (green) colonies in the Americas around 1763 and Africa and overlaid with pie charts depicting the relative proportions of mtDNA variation in the pool of African-derived mtDNAs of USA, Philadelphia, Caribbean, Cuba, Colombia, and Brazil derived from corresponding regions of W/WC, SW/WC Bantu, and SE Africa. Enrichment of American variation from source African colonies is particularly visible on Brazil and Philadelphia that have drawn most of their variation from Portuguese or British colonies.
