My MDLP World-22 Admixture Proportions
However, if my results are checked by each chromosomes, I have a % in each one of the above categories.
mt-Haplogroups A & D are in the Arctic, Southeastern U.S. & South American (Native American markers). The most frequent in the U.S. are A, B, C, & D with a smaller number X. The first 4 are found on each side of the Bering Strait. Not so with X.
