What will a Y DNA test tell me?

A Y chromosome DNA test (Y-DNA test) is a genealogical DNA test which is used to explore a man’s patrilineal or direct father’s-line ancestry. The Y chromosome, like the patrilineal surname, passes down virtually unchanged from father to son.

How accurate is Y DNA testing?

Y-DNA testing results are normally stated as probabilities: For example, with the same surname a perfect 37/37 marker test match gives a 95% likelihood of the most recent common ancestor (MRCA) being within 8 generations, while a 111 of 111 marker match gives the same 95% likelihood of the MRCA being within only 5 …
