Ancestry Map (IMAGE) University of California - Davis Caption A distinct DNA signature was found among all but one of the populations shown as points 32 to 53 on this map. The Fox tribe, point 48, was the exception. But DNA samples of only 2 Fox people were tested -- too few to provide a valid result. The DNA signature was absent in all Asian groups sampled, points 1-32.
