Welcome to the X-chromosome Project!  The goals of this project are to provide a place for people to gather and discuss any issues or topics of interest relevant to the human X chromosome, and for people to share and compare their X DNA test results.

The X-SNP data, which is no longer being updated due to incompatibilities of the latest chip versions with the original data format, has been archived at:

The X-STR results can be viewed by clicking the "X-STR Results" tab in the navigation bar at the top of this page.

To visit the project's forum from any page, click the "Forum" link on the top navigation bar.

Please ignore the "Order Test" link in the top navigation bar, as this project is not currently linked to a valid order page at FTDNA.  If you would like to order a test kit, feel free to contact me, letting me know what kind of testing you are interested it (e.g. X-chromosome tests, Y-DNA tests, mitochondrial tests, etc., or ask me if you are unsure), and I will direct you to the appropriate page.
