Um. I was assuming that Lee Anne meant what she said: "not listed as
a 12-marker match." The genetic distance at 25 markers was 1.
Therefore, the genetic distance at 12 markers must have been at most
1, and the viewer would have to scroll past *all* 12-marker matches
and near-matches in order to see the 25-marker list. Ah, but there is
another possible explanation -- if there were too many matches, the
list would be truncated unless the viewer insisted on seeing the whole
