They don't interpret the markers. They just estimate the percentages
of overall admixture. Then again, I happen to know that they have
experimented with reports that do include marker-by-marker interpretation,
but what I've heard does not indicate a truly meaningful product.
In any case, the long list you received is a list of *their* numbers
for the markers they use. As Ann explained already, the true identities
of most of the markers are secret.

The statistics end of things is dead simple. I posted a tutorial
here a year or two ago that worked through a simple example of the
estimation technique. See the archives.
