There are the autosomal tests done by 23andme.com and ftdna.com (they call
it Family Finder). 23andme has lowered the price to $99, which is
fantastic.
These tests look at the autosomal chromosomes which are passed from mother
and father in a rather random fashion. You can't describe the lineages in
the way you can with the Y chromosome of mtDNA. It makes predictions by
how closely two people are related by the length of matching DNA segments.
But those segments could have come from either side of the family for each
generation. And, my understanding is, that its good to only about five
generations or so--the matches become too small and fragmented to make any
real prediction.
Not only do we get half of our DNA from each parent, but half of is is
"lost"--and which half we get is random and changes between siblings. So,
it's possible that you might have some match segments to me, for example,
but none to Jim (through Perrin's son John). That would not mean that
you're closer related to me or not related to Jim, just that the segments
are lost or preserved randomly.
I know, it's confusing. It might help to reiterate that the Y chromosome
is passed strictly from father to son. (It carries the male gene so women
do not inherit it.) The Y doesn't go through the recombination that the
autosomal DNA does and is passed down as a virtual clone--and remains that
way for generation after generation. (I've recently read, btw, that enough
mutations are introduced over 15 generations that it ceases to be an
effective indicator.)
I hope that those many words came close to answering your question. If no,
ask away.
