FTDNATiP™ (FamilyTreeDNA’s Time Predictor) is a program that predicts the time to the most recent common ancestor for two men based on their Y-chromosome STR matching and STR mutation rates. FTDNATiP™ provides powerful and precise calculations of Time to the Most Recent Common Ancestor (TMRCA) by incorporating mutation rates specific to each STR marker.

To use FTDNATiP™:

1. Sign in to your myFTDNA account.
2. On your dashboard, select Matches in the Y-DNA section.
3. On Y-DNA – Matches, click on the orange TiP icon next to a match’s name to run the FTDNATiP™ report for that match.
