Hello! This project is open to men and women who have mtDNA testing at Family Tree DNA, confirming assignment to mtDNA Haplogroup I. (MtDNA testing from other companies does not transfer to FTDNA because it is incomplete with large gaps.) Your mtDNA is passed down through your direct MATERNAL lineage, which is your mother's mother's mother's line. (There is a separate and unrelated Haplogroup I that is determined through male Y-DNA testing and has its own set of haplogroup I projects for its various branches.) The Project Respects Your Privacy: We NEVER share your name, email, ancestral surnames, family tree or coding-region mtDNA data with anyone. Sharing of limited data is in your control based on your account settings that always default to be private. For an excellent introduction to Haplogroup I and to the project, please see the project pages (links at top of page) entitled "Background" and "Results." Feel free to email me (Martha Hicks) with any questions. .
