The Big Y-700 test is a Y chromosome direct paternal line test. It is designed to explore ancient ancestral links on our common paternal tree. This test examines thousands of known branch markers as well as millions of places where there may be new branch markers.
The Big Y test is intended for expert users with an interest in advancing science and anthropology. It is not a test for matching you to one or more men with the same surname in the way that other Y-STR tests do, such as Y-37, Y-67 or Y-111.
