Last year, Ancestry released a tool that allowed them to paint their
ethnicity results onto your chromosomes. Now, I reviewed that in a previous video,
but what we're going to go over today is the DNA Painter tool called Ancestry DNA
Chromosome Painter segments. Now, this starts really with
information from Ancestry. And I'm actually going to be
using a friend of mine's because my results from Ancestry are very homogeneous as far
as each one of the chromosomes. Whereas my friend here, you can
see her chromosomes are divided up into multiple different colors all throughout.
And so I thought I'm probably going to get better results with this here.
So on DNA Painter if we go down and we look at the Ancestry Chromosome Painter
segments, we can click on this. And they have a blog that goes
over what I'm going to be talking about here. But in general, this is what we need to do.
We need to copy the contents of your Ancestry DNA Chromosome Painter page
and paste them in the box below. Now, you may have never done this.
They give you great instructions that walk you through this.
What you need to do is,
on the Chromosome Painter page make sure that you clicked on that.
Do a Control + A and that Control + A means that you're going to highlight everything on there.
You can see it looks like all the text is highlighted.
It doesn't look like these graphics are highlighted, but don't worry they are.
We want to copy that. So, Control + C to copy
everything that we've just highlighted. We're going to go over to DNA
Painter and we're going to paste it. And that's Control + V (as in Victor).
And just like that, you can see the screen changed.
It says my segments are extracted. It's gone in red everything that it
needs to, and then you have two options. You can either create a new chromosome map
or you can download the segments and then to add this to an existing map.
This is where what we're going to do.
We can use the import the segment data that's only available to DNA
Painter subscribers or we can paint the segments individually via a paint a match.
So, let's go and download the segments. And you see there was a new CSV file here.
And that is what we are going to upload to one of our maps on Chromosome Painter.
I'm going to open up this file.
So, you can see what is in it. And we can see that, hey,
there's a chromosome A start and end and the group.
Then there's also this color and standard- the Ancestry side whether it's paternal or maternal.
This information in the standard, the color. And the Ancestry side- We're not going to use.
We're just going to copy this first bit chromosomes start and and the group.
So, let's open up this file. Now, one of the things that is
a little bit tricky here is we want to actually put these in group by group.
In other words, we can't just put everything in at once.
We've got to put in each group one at a time. So, I am going to make an auto filter on this.
And now, I can start with the first one and I'm going to go with the Nigeria paternal group here.
So, let me scroll down and find them- Nigeria paternal.
And this is everything for Nigeria paternal. And then I'm going to highlight the A, B,
and C columns. Okay.
Now, I can go back to DNA Painter.
So, on DNA Painter we're going to go over to chromosome maps.
And I'm going to select the map I want to add it in.
And in this case, this is my sandbox that I'm using.
And I can paint a new match up here in the corner. Let me paste that data in and let's preview
these segments. All right.
It has 52 new match segments. They're overlaid below.
And you can then take a look at them. Just save them all if you want.
In this case, I'm going to look at this your magic blue segments that overlap the following groups.
Well, let me just save these segments to this match.
Now, I know how I'm connected to this match. I don't know how I'm connected to this match.
But what I do know is from Ancestry that says this was the paternal side.
And so, I'm going to mark that as paternal.
If you didn't know, you might want to just leave that blank until you have that.
So, I'm going to put Nigeria here. So, this group is Nigeria.
And then I will, you know,
what though I'm going to label it Nigeria paternal and then I can save this match.
Now, it's added all of those in and you can see it is this brown.
And now, I can go through on my map here and I can see, hey, are there any
people on the paternal that are related? And you can see, hey, some of these are.
Now again, this isn't accurate because it is not the same DNA
matches that are being looked at here.
I've taken somebody's ethnicity and matched it over somebody else's matches.
But you get the idea that you're using these ethnicity results.
Download as a separate way of looking for how your matches might be related to you.
And we can go and upload it and we see that, hey, this is now 85
segments. It's gone up to 35 percent. You can see actually how that all falls
in there and the other matches that are overlaid and underlaid on these as well.
Ancestry DNA's Chromosome Painter is still in its infancy right.
Now, what I would like to see in the future is whether or not we
can import the data from 23andMe which also has the same thing.
I'm not sure if DNA Painter's working on that, but I'd also like to see
improvements to Ancestry's Chromosome Painter. When it starts to look more like what 23andMe has,
I will be more confident that it is real reflection of reality.
But right now it is another way to look at some data.
And some people's ethnicity breakdown by chromosome may
actually be more accurate than what I was seeing on my own.
So, if you haven't tried this tool on DNA Painter, then log on to DNA Painter and try it out.
Now, if you want to check out another tool, you can look at this video right up here.
