In order to provide our customers with the highest level of haplogroup confidence, Family Tree DNA provides a SNP Assurance program (beginning with batch 173). If a person’s Y-DNA haplogroup cannot be predicted with 100% confidence, the SNP Assurance Program will test your sample with our Backbone SNP test for FREE. Specifically, if we cannot predict a person’s Y-DNA haplogroup with sufficient 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. Backbone tests take about 6-8 weeks from the time they are ordered

We test a panel of SNPs in order to determine your placement on the haplogroup tree. The positive value for the SNP that determines your haplogroup assignment is reported on the Y-DNA – Haplotree & SNPs page of your myFTDNA account.

The following depth of haplogroup prediction or confirmation is guaranteed for all Y-DNA tests.

If you tested before we implemented the SNP Assurance Program, and the Y-DNA – Haplotree & SNPs page of your myFTDNA account shows your haplogroup as unpredicted, then we will run the Backbone SNP test for you. Please use the feedback form to send your request to our customer service.
