The Y-DNA TiP page allows you to calculate the likely time to a common paternal ancestor for two project members with Y-DNA test results. Report options are:

  • Markers: Select the testing level for calculations.
  • Compare: These are the two men who will be compared.
  • Unrelated Generations: If the paper trail indicates that no common ancestor could have lived in a certain number of past generations change the “They do not share a common ancestor in the last # generations” number to refine the calculation.
  • Display: Select the interval for calculations. 

Note: The number of generations between which mutations could take place is the important factor in calculating the time to the Most Recent Common Ancestor. The number of years per generation is irrelevant in FTDNATiP calculations.
