John,

When the basis for comparison is the single most common 12-marker haplotype in
the database, you would expect the number of matches to drop with any move away
from that haplotype. Apparently, for the haplotype in your project that has a
GD of 1, whatever marker it is that's off the modal makes the haplotype
instantly uncommon.

While many R1b haplotypes are common, there are also many 12-marker R1b
haplotypes that are uncommon, rare, or even unique, with no match, at all. Out
of seven R1b1b2 families in my CORBIN project (n=16), there are three unique
12-marker haplotypes.
