  • Not a single match?

    I am a Group Administrator and one of my members does not have a single match. Not even a Y-DNA12 match.
    Am I correct in saying that there's only an extremely low probability of this happening? Did something go wrong with the testing? What does it mean?
    I'm no expert in this field but it strikes me as very strange that someone does not get a single match.

    I meant to say, not a single near-match either

      It isn't common but I have more than one person in my projects who has no exact or near matches. This usually happens in the less common Haplogroups.

        But it can happen with common haplogroups also. I am an L21 with no matches.

          This is also checking for everyone in the FTDNA database?

            Yes, that's comparing him with the entire FTDNA Y-DNA database - not a single match nor a near match, even at the 12-marker level. And he's a very common R1b1a2, Shorthand R-M269!

              I have about 6 men in 3 of the projects I admin, who are all R1b (M269 at least), they have no matches at all, at any level, with any surname.
              I have 2 relatives with only an 11/12 match, they are R1b M222 and I1 L338.

              They are all from the UK/Ireland and compared against the entire FTDNA database.

                How about on Ysearch? (which includes some non-FTDNA results as well)

                PS: Can you post the markers and values. There may be some quite rare combinations in his 12 markers set.

                  I have a rare DYS385b = 21, which limits my 12 marker matches to just one against the entire base. If it were either 15 or 18, I'd have hundreds of matches; in fact, if it were 15, I'd be a perfect match to the 12 marker CMH. But there are a few guys who share a motif with me and we've been clustered together in the J Project. Conversely, one of my cousins, a proxy for my maternal grandfather, has 174 12 marker matches, but I haven't learned much on his origins beyond the major subclade he belongs to.

                    Here are his results:

                    PANEL 1 (1-12)
                    Marker DYS393 DYS390 DYS19* DYS391 DYS385 DYS426 DYS388 DYS439 DYS389I DYS392 DYS389II
                    Value 13 24 14 10 10-14 12 12 12 14 11 30
                    PANEL 2 (13-25)
                    Marker DYS458 DYS459 DYS455 DYS454 DYS447 DYS437 DYS448 DYS449 DYS464
                    Value 16 9-10 12 11 25 15 19 28 15-15-17-17
                    PANEL 3 (26-37)
                    Marker DYS460 Y-GATA-H4 YCAII DYS456 DYS607 DYS576 DYS570 CDY DYS442 DYS438
                    Value 14 11 19-19 15 15 15 17 36-38 13 11

                    Sorry if this is a bit difficult to read. I can't find any better way of exporting the results.

                      Putting his first panel into Ysearch returned just one hit: a 9/12 match with ID N3YB3 (Mallard) who tested with Genebase. The 3 markers not matched are DYS385a&b and DYS392. I don't know if Genebase tests for those markers.

                        My brother has only 1 match at the 25 and same one at 37 otherwise none. He was disappointed. I told him he was "one of a kind"

                        That side came to USA in 1885 from Germany.

                          I have quite a number of project members who don't have any matches at 12 markers, including a number of R1b1a2 men. Most of the men in my projects who don't have matches live in the British Isles. It seems to be quite rare for Americans not to have matches unless they belong to a population group that is under-represented in the database (eg, India).

                            Brother is R1b1a2 -- we'll just hope more people from Europe test so we find out great grandfather and back, but in the meantime try to find a paper trail.

                              I have no matches. Only have 12 markers results so far. Father's paternal line etc came from Ireland. Exported to Y-search, some near matches (?) of 10 or 11.
