During the recent 3rd annual Family Tree DNA genetic Genealogy Conference we announced that if we could not predict your Haplogroup with 100% confidence, we would run your DNA sample through our Back Bone SNP test for free.
In order to provide our customers with the highest level of haplogroup confidence, Family Tree DNA is now providing a SNP Assurance Program.
In this program, 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.
The following depth of haplogroup prediction or confirmation will be guaranteed for all new Y-DNA tests beginning with batch 173:
A, B, C, D, E, E3a, E3b, F, G, H, I, J, K, K2, L, M, N, O, P, Q, R, R1a, R1b, R2
When a haplogroup is in doubt the Backbone SNP test will be ordered automatically.
The level of guarantee will be reviewed annually and presented at subsequent FTDNA Genetic Genealogy conferences.
What are haplogroups?
Haplogroups are genetic population groups that identify where in the Y-DNA or mtDNA tree of humanity you fit in. Haplogroups are what allow us to identify how large groups of people migrated from Africa around 60,000 years ago to different parts of the world.

What is a SNP?
A SNP, or Single Nucleotide Polymorphism, is a change in your Y-DNA sequence at a location other than those in the 12, 25, 37, and 67 marker tests. SNPS are unique to specific haplogroups so SNP tests such as the Backbone and Deep SNP tests are used to identify haplogroups and their subclades respectively.
What is a 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.
