From: Darren Marin To: darren@familytreedna.com Sent: Tuesday, July 24, 2007 9:26 AM Subject: Family Tree DNA - Haplogroup Nomenclature Change Dear Family Tree DNA Customer, Your haplogroup was determined to be E3b or one of its branches by a SNP test you had performed with us in the past. While your test results have not changed, we now have a more specific branch assignment due to more recent research. We are updating all individuals in haplogroup E3b or one of its branches in our database. The following list shows which haplogroup names are changing, and what they are changing to: E3b is now E3b1 E3b1 is now E3b1a E3b2 is now E3b1b E3b2b is now E3b1b2 E3b3 is now E3b1c E3b3a is now E3b1c1 Although the haplogroup classification does and will continue to change as the haplogroup tree evolves through research, your actual test results of what you are positive and negative for has NOT changed. We will update your specific haplogroup definition automatically in the future as the tree evolves and in agreement with scientific papers. Family Tree DNA
