  • Family YDNA Matches

    Hi

    If two brothers to the same parents took a YDNA37 test would I be expecting to see the exact same DNA test results when they came back? All 37 markers are identical or is there always some genetic variation between siblings?

    In most cases they should be an exact match but don't get nervous if they don't match.

        My brother and I are 36/37. So mutations can happen at any point in time.
