Just got back the results of my Y-67 upgrade, and my closest match is someone who has only tested to 37 markers. We have a 36/37 match.
Since I was adopted and don't know my father's surname, I am hopeful that there is a good possibility it was similar to that of my 36/37 match. According to the "TiP" which shows the probability of various genetic distances between us, there is a 56% chance we share a common ancestor in the last 4 generations, 86% chance in the last 8 generations, and so on.
But my question has to do with the one marker, DYS464, where our difference shows up. I know this marker is duplicated at four locations, hence the four numbers that appear there. I've read this is the most polymorphic marker, or the one that changes most quickly across generations. Some companies apparently don't even use this marker to determine time to most recent common ancestor.
So can I infer from this that since the one marker that is different is part of this polymorphic DYS464, that the most recent common ancestor with my match may be closer than indicated by the "TiP"? Is this one value out of four equivalent to one fourth of a marker? Or is it best not to attempt to read much into it?
My match has only done the Y-37 test and not FamilyFinder. Would it be a good strategy to have him do FamilyFinder to see if we are close or not, or would it be better to test more Y markers? Or both?
Thanks.
