Phil

haplotype - haplogroup correlations arise from "founder effects" in which an
individual lineage with distinctive SNPs and STR values comes to dominate a
population in which it was originally only one of many. This could be
through a reduction in population size followed by expansion again (also
called a "bottleneck") or when a group breaks away to form a new
geographically separate population. The smaller the founding group (or the
"neck" of the bottleneck), the more likely that it is not representative of
its parent group.
