I'm reading up on them at the moment as I'm trying to learn more about Chromosome22 Ring. There's something basic that I don't understand. In the label 16p13.3, for instance, I know that the 16p refers to the shorter, upper arm of chromosome 16 & I think that the 13 is the specific locus. But what is the .3 on the end? What does that refer to? I can't find it anywhere.
