You might have heard of a doppelganger, but what about an evil twin?
Howdy, I'm Andy Lee with Family History Fanatics where we help you understand
your DNA, climb your family tree, and write your ancestors story along the way.
This is a segment of DNA. Be sure to subscribe to our Channel and click on
that bell if you want to be notified about upcoming episodes. Some of you may
have met my twin Phil, now he's not really an evil twin he's pretty much
harmless, but in GEDmatch you can use your DNA to create an evil twin and
that's perfect for Halloween just coming up. On GED match I have
logged in and if I scroll down I'm gonna see that the free tools are under DNA
applications, but your evil twin you need to be a tier 1 member. So if we scroll
down a little bit further we get to our tier 1 tools and we can see there is my
evil twin, this is the tool we're going to be using today. My Evil Twin is sort
of like phasing except that instead of seeing what parts of DNA you got from
your mom and what parts of DNA you got from your dad My Evil Twin tells you
what parts of DNA you didn't get from your mom and what parts of DNA you
didn't get from your dad. So in order to use this tool you need to have your kit
and then you need to have at least one parent kit and if you have two parent
kits that's even better. Now it does divide out into your
father's kit and your mother's kit, so if you only have one parent make sure that
you select the correct parent otherwise it's gonna give me an error saying that
it's not the right sex of that person. Now this idea was from Tim Janssen
originally and special thanks to him for thinking about hey this data actually
can be useful for DNA research as well. And it only takes a few seconds and your
kit has been created, now it's going to have a number of your kit number and
then m2 for your maternal side and p2 for your paternal side. Now the phased kits
are going to be m1 or p1 if you've used the phasing tool to phased your DNA. As
with all of the kits whether you upload them or create them they are ready for
one-to-one comparison immediately and then within a couple of days you'll be
able to use the one too many, but let's go take a look at our one-to-one to see
how this DNA looks. So the first thing I'm going to do is I'm going to compare
my maternal phased kit to my maternal evil twin ki., Nnow since one kit is what
I did inherit from my mom and the other kit is what I didn't inherit from my mom
there should be no matching segments on that DNA unless there is some multiple
relationships or some endogamy in my background. Now, I don't have any known
endogamy in my background. So let me just go down and scroll through here we
can see, yeah it's looking like there are no matching segments anywhere. So, it
found no matching segments in all that comparison so My Evil Twin and me we
don't share any DNA from my maternal side. Now let's take a look at my
paternal side and see if My Evil Twin and I share any DNA and no we don't
share any DNA. So this is exactly what we would expect for people who don't have
multiple relationships in their family or endogamy in their family that is
somewhat recent. Your evil twin and your face kits should be the exact opposites
of each other. Next, I want to compare my phased kit and My Evil Twin kit to my
grandfather. My father didn't receive all of my grandfather's DNA so I don't
expect to see everything being covered here, but what I do expect to see is that
in the places where there was DNA inherited
it's not going to overlap between my phased kit and My Evil Twin kit because
they should be the opposite. So as I'm looking right here I can see on
chromosome number two the phased kit has a little bit which is a match
with my grandfather and then there's the evil twin kit which shows all the rest
of it that is a match with my grandfather as well. So I didn't inherit
where this light blue is but I did inherit where this dark blue is. And we
can see that in various places on this map as we go down there's not sections
that are big overlapping, you might see just the tail ends of sections
overlapping, but the most part these are all segments that don't overlap between
these two because they shouldn't because they're looking at different DNA. Next
I'm going to look at a distant cousin and this is comparing his DNA to my
father and then it's also comparing it to my phased kit and to My Evil Twin kit.
So as I'm going down I can see a couple of things. First off on this first
chromosome number seven there is a little green bar that is here for
numbers 1 & 2 which is going to be my evil twin kit so I didn't inherit that
part but my dad did and so that's picking up that, but then as I go further
to the next chromosome I can see that there is a part that I inherited and my
dad inherited as well. Down further on chromosome number 13 here's another one
that My Evil Twin got that I didn't get so this is another segment that is lost
between my father and me. And then finally on the last chromosome number 16
this is another segment that is lost between me and my father My Evil Twin
inherited it but I didn't inherit it. Evil twins are a phased kit there are
some specialized uses where you would use them in genetic
genealogy that I'll make in videos later on, but for right now just understand
that it is taking the DNA that you didn't inherit from each of your parents
and creating kits that look like that. So if you have any questions about your
evil twin put it in the comments below and I'll try to answer it and if you
like this video be sure to give it a thumbs up and share it with all your friends.
