A word about the rate of change of the value of the different markers (DYS#) - familytreedna.com (where all these tests were done) will release info pertaining to the rate of change (mutation rate) based only upon groups of markers rather than by individual markers. The mutation rate for markers 1-12 is 0.0039, for markers 13-25 0.0048, and for markers 26-37 0.0075. These figures represent the possibility that there will be any change at all within the group of markers from one generation to the next. So, over the course of 10 generations, for example, there is a .039 (or 3.9%) chance that the value of any marker within group 1-12 will change from the 10th generation male of that line to the current (1st) generation male of the same line.
