In addition to the standard 12, 25, 37 and 67 yDNA marker tests offered by FTDNA, there are quite a few tests of other markers offered in their Advanced Tests menu. Here is a link to a page put together by another DNA project administrator, Diana Gale Matthiesen, that explains these advanced tests. If you have any questions, please do not hesitate to contact us. Keep in mind that you must have already taken one of the standard tests through FTDNA before you can order any of the advanced tests.
