It is a group of closely related mtDNA types. "Haplo" because mtDNA is
by and large a single copy system where a person only has one mtDNA
type, and "group" as opposed to "type," when we lump similar types
together. The haplogroups were assessed from studies of populations
with multiple samples. The labels of the groups are still labels of
the haplogroups even when you are discussing one particular person.
