How does this help one's genealogy? I heard you can see where you and someone else like Royal shared a common ancestor at one point. Can it extend your genealogy any further by doing this?

since I just woke up and you just posted this I'll toss in a comment but
I'm by far no expert in DNA (I've CC'ed Gary Felix - Hi Gary. . .Feliz
Navidad - of the Mexico DNA project to comment if I totally miss the
boat on something: very possible):

to help your genealogy along using DNA you want to work with a Y-DNA
work up which is the one passed along through male individuals from
father to sons. mt-DNA is passed on from the mother to both sons and
daughters. So you can do your Y and mt DNA, but from my understanding
Y-DNA is much closer in time span to our present time while mt-DNA skips
back many many thousands of years back so it is harder to find a match
with someone who you can prove is your relative via a written document.

So what you do is have the 25 or 37 marker or even the next one 67?
marker test (the more markers the more likely you're a match if both
indivduals test the same). And you use it to compare first with
indivduals that have the same surname and you think might be your
relatives. If you all come up a match then you are related.

Then the way you advance your genealogy is to hope that the person you
matched up with has advanced their genealogy in a direction that will
help you. Otherwise you will be the one to help them. Then again on some
lines maybe you'll be able to help each other.

well I'm sure I might have worded wrong and I'm hoping others will comment.
