Mitochondrial DNA variation in the Senegalese and Philadelphian populations.

Major mtDNA haplogroups present in Philadelphian African American (AA), European American (EA), and Senegalese samples. The phylogenetic details are depicted in the tree in Figure 1 and the sequences presented in File S1.

(*Note: Although haplogroup U is of Eurasian origin, we placed the U6 and U5b1 haplotypes under “Africa” since they are commonly found in North African populations).
