The new Big Y Test from Family Tree DNA
Big Y. The new test uses next generation sequencing technology which is much more reliable for the Y-chromosome than the chip testing used for the Geno 2.0 test from the Genographic Project and the Chromo 2 test from BritainsDNA. The Big Y is intended as a replacement for the Walk through the Y test which used the slower and much more expensive Sanger sequencing technology.
The Big Y test covers 10 million base pairs. It will provide results for almost 25,000 of the known Y-SNPs. However the exciting part is that this test can also be used for SNP discovery, opening up the tantalising possibility of finding SNPs that will prove to be unique to a particular surname lineage or an individual branch of a family tree.

Big Y matching is coming! Over the course of the next two weeks we will begin a phased release of Big Y matching so you can directly compare your comprehensive Y-DNA results to those of other Big Y test takers. The key to identifying all new SNPs and subclades is finally here!
Family Finder was recently improved with the release of my Origins, an all new ethnicity tool allowing you to compare your ethnic breakdown to that of your matches while providing more detailed information on your ethnic heritage than ever before!
