Not per se. But there is plenty of evidence that higher numbered
alleles for a given marker mutate faster than lowered numbered ones. Hence,
a haplogroup with typically higher allele counts will have that marker
mutate faster than a haplogroup with typically lower allele counts. This is
only a simple relationship for "simple" markers, that is, ones with
a single unbroken run of a single variable unit.
