What is a Y-DNA Backbone test?
A Backbone test determines which haplogroup, or major branch of the Y-DNA tree, your paternal line belongs to. It tests the “backbone” of the tree or the SNPs that determine the major branches. For a more detailed explanation of haplogroups, please check here: http://www.familytreedna.com/understanding-haplogroups.aspx. In order to provide our customers with the highest level of haplogroup confidence, Family Tree DNA provides a SNP Assurance Program. In this program, if we cannot predict a person’s Y-DNA haplogroup with extreme confidence that they can join the National Geographic’s Genographic Project, we will automatically perform a Backbone SNP test in order to identify the haplogroup assignment. When a haplogroup is in doubt the Backbone SNP test will be ordered automatically after the initial Y-DNA test results are posted. You can learn more about the SNP Assurance Program here: http://www.familytreedna.com/snp-assurance-program.aspx. Members will still have the option to order a
