The distribution is normal-ish except it has to peaks at 4 and 6. GD of 5 seems under represent if the distribution of GD is be a perfect bell curve. Could there be two normal distributions centered on GDs of 4 and 6 (of equal weight)?

A normal distribution centered around a GD of 5 I am thinking that is less than a thousand years? So I am confused?

I know some of the direction of this 'Mean' GD of 5 has been identifed in previous emails; with certain differences to central M222 modal in DYS values common to certain family names? Ewings for example: DYS 19/ DYS 439.

When I first read of Y-DNA testing I read that DYSs has a equal chance on a mutation that increased or descrease DYS number. Yet our halpogroup (defined by mutation M222) is identifiable by a defined halpotype. This should not be the case if movement of DYSs values were random? So there is 'drift' in mutation in DYSs values? If so is there an explaination for the drifting apart of of halpogroups's halpotypes?
