The Big Y product is a Y-chromosome direct paternal lineage test. We have designed it to explore deep ancestral links on our common paternal tree. Big Y tests thousands of known branch markers as well as millions of places where there may be new branch markers. This product is intended for expert users with an interest in advancing science.
It may also be of great interest to genealogy researchers of a specific lineage. However, it is not a test for matching you to one or more men with the same surname in the way that our Y-DNA37 and other tests do.
