True, but note the problem with so-called UEPs for genealogy: they can
only be "useful" to confirm what is already known by other means. For
example, if a battery of STR tests shows that two men are almost surely
connected within the past 2000 years, but a UEP test supposedly says
that they cannot possibly be connected within the past 5000 years, the
inescapable conclusion is that the UEP test suffered from a lab error,
or conceivably uncovered a parallel mutation.
