The median mutation rates (without interpolation) are:
12 (1-12) 0.0020
25 (1-25) 0.0025
37 (1-37) 0.0040

So, very interesting Charles!

It seems as one adds more markers the mutation rate goes up! So the 1-12
with 25 samples at 0.0005 and the 1-25 with 12 samples at 0.0005 are
skewed to the low end and are not really representative of the actual
mutation rate that one finds with a larger marker set (the 1-37)?
