YSTR marker DYS425 is part of the 67 marker panel tested by FTDNA. Note: Existing FTDNA customers can conveniently join this project using the blue JOIN button at the top of their personal FTDNA test results home page. Only YDNA test results found in FTDNA's test results database can be used to join this project.
