Eh? I don't follow. At 67 markers, a close match is a close match. Why would it matter how many have matched in total? If you were to match 64 out of 67 all with one step differences, for example, it would indicate a common ancestor within the past few hundred years, even if there were fifty men in this cluster. They would all be related within a genealogical time frame.



12 markers with a difference of 2 - sure, convergence is a good possibility. 67 at a GD of 2 - not a chance.
