  • Interpreting genetic distance with Y DNA test

    I recently got back my Y67 test. At that level my top three matches all have a genetic distance of 3. My top match is a different surname than what is prevalent with my other closer matches.

    However, at 37 markers, my 2nd and 3rd closest matches at 67 markers are at a genetic distance of 1, with my top 67-marker match at a genetic distance of 2.

    How do I interpret this? The explanations of genetic distance for each of the markers counts to a common ancestor seem at odds with each other. I'd like to better understand this conflict of sorts.

    I'd appreciate any knowledgable reply.

    Thanks!
