On the Genetic Distance page, there is a limit on the maximum genetic distance between the project member you have selected and those who appear on the comparison list. The maximum genetic distances are:

  • Y-DNA12:  3
  • Y-DNA25: 5
  • Y-DNA37: 7
  • Y-DNA67: 25
  • Y-DNA111: 40

The maximum genetic distances have been set to be more than what one would expect to find in the genealogical time frame and for higher testing levels, the historic time frame.
