Beginner's question: I had a 12-marker Y-chromosome test at FTDNA. I expected to have lots of exact matches, and then upgrade my test to eliminate them. I was surprised to learn I had no exact matches at all.

This seems to lead to a natural question: how many different possible values are there, for the 12-marker test? (And how many of the possible ones are represented in the FTDNA or ySearch data?)
