Lineage D2 sequence variation in Aleuts and Siberian Eskimos. “M” is macrohaplogroup M, which is shared by all of the Aleut and Eskimo mtDNA samples. Four diagnostic variants for haplogroup D mtDNAs are underlined. These were inferred through comparisons with four complete sequences (three Native Siberian and one Native American mtDNA) belonging to haplogroup D lineages other than D2, as well as with the data given by Herrnstadt et al. (2002). Asterisks (*) indicate the Aleut-specific 8910A transversion. Only those nucleotide positions that differ from the Cambridge Reference Sequence (Andrews et al. 1999) are shown. Mutations are transitions, unless specified explicitly. The Aleuts were sampled in the Commanders, and the Eskimo sample consists of Sireniki Eskimos from the Chukchi Peninsula. Note that site 8683 AluI+, reported by Starikovskaya et al. (1998), was incorrectly mapped and, instead, is 8700 AluI+ (because of transitions at nps 8701 and 8703).
