As a Haplogroup Project, The C-P39 Y-DNA Haplogroup Project serves the genetic genealogy community by:

• Exploring the history of the Haplogroup since its members' most distant shared ancestor.
• Tracking the geography the Haplogroup and its subclades.
• Examining the age of the Haplogroup and its subclades.

The project is open to all Family Tree DNA clients who meet one of these qualifications:

• Have tested positive for P39 at Family Tree DNA or be predicted positive through their system.
• Have tested positive for P39 at another lab and send a copy of their results certificate to project administration.
• Have a positive Y-DNA match who shares a paper trail ancestor in under eleven generations.

If this describes your kit or a kit that you have proxy rights for, you may join by following this link and filling in your kit number and password. You do not need to order a new kit.

In addition to the Family Tree DNA Administrator's Guidelines, the project shall:

• Inform all project members before allowing their results to be used outside of the project.
• Inform all project members of policy changes.
