  • ISO document that discusses mutation rates/patterns for each DYS#

    I know awhile back I'd seen here somewhere on the forum a link to an article or web site that discusses each (or at least many) of the DYS markers, their mutation rates and perhaps (not sure I remember accurately) more about the meaning of changes at one marker vs. another... If anybody knows what I'm recalling and could point me in that direction, I'd be very appreciative.

    I spoke with the granddaughter of my closest 37 marker match today, and now I know which markers we differ at. Just curious; trying to cultivate a hunch about how close we might be. Neither of us has a paper trail - my great grandfather left Denmark leaving us no clue as history or ancestry (or even name with certainty) and her grandfather never knew his father or who he was.

    Thanks!

      Well, no, this isn't what I saw before but this is great too. THANKS!
      (What I'm remembering was not a table but a several pages long document with prose description.)

          Hmmm... well, it may be. I'm less certain now about what I had seen before.

          There are 3 of us now, we are each other's closest yDNA match. The other two are closer to each other (35/37) than I am to either of them (34/37 with one, 60/67 with the other). (Yes, the 3d person is going to upgrade to 67 markers).

          I am interested in triangulating our three sets of results to learn the most from it that can be learned - so I'm looking for specific discussion of specific markers. The table referred to above will obviously be helpful. But if anyone knows of a discussion of the 'personality' of the various markers, and what a particular variation on particular markers might indicate in terms of how closely or distantly we are related, I would appreciate it. (As I write that I realize it's wholly bound up with the assumptions behind the FTDNATiP calculations. I don't see those secrets revealed in the FAQ, however)

            And they're not likely to be, I think. Here's a quote from the general roll out announcement in 2004:

            FTDNATiP is a proprietary algorithm developed by Family Tree DNA in conjunction with our Advisory Board Member, Dr. Bruce Walsh, a leading population geneticist.
