Ann,

Based on my observations, I would say Bruce Walsh's assertion is true, but
also more rare than mutations on fast-mutating markers. Please see kit
D69ZFH4 under the "Gough/Goff, Eastern VA" category at
http://home.comcast.net/~philgoff/DNAresults.htm and notice that this kit
matches kit F46098 (immediately above it) on all markers by YCAIIb, which is
a slow-mutating marker. As all other markers agree and both partipants have
paper trails to the common ancestor, this is taken to be a match. However,
IMO, this is really the exception where the clock on a slow-mutating marker
happened to tick very recently, before fast markers had a chance to mutate.
On all other family groupings on this page include either exact matches
across all tested markers or mutations on the fast-moving markers. I would
say the latter situation is more of the norm than the former. Thanks,

Phil Goff
