Subject: Re: [DNA] variability in DYS464

There are a handful of members in the R1b project that are not
R1b1c. Because there appear to be several P1/P2 RecLOH events
between R1b and R1b1c, it would be wise to exclude the R1b1* and
R1b1b members of Charles project if your goal is to understand the
mutation rate of these markers.
