The AncestryDNA Chromosome Painter feature is an exciting, useful new tool that can help us learn more from our DNA results. Learn details about how to find and use this feature in this easy-to-read article.
I did my first DNA test with Ancestry back several years ago, and since that time, they have rolled out tons of new features that have helped me get more value from that initial test. The new Chromosome Painter tool is just one of the many new features that I’ve seen developed on Ancestry over time.
However, the Chromosome Painter is a really big deal for those of us interested in genetic genealogy. Being able to view our ethnicity inheritance on the chromosome level is going to be a game-changer for those of us trying to break through some of those tough family tree mysteries.
But I’m getting ahead of myself. Let’s get started learning the basics of this new tool, shall we?
What is the Chromosome Painter on Ancestry DNA?
The Ancestry Chromosome Painter tool is a feature that leverages data from millions of DNA tests and family trees to visually display ethnicity inheritance on each copy of your 22 numbered chromosomes. This feature will help you learn the general location of DNA segments matching the ethnicity regions that show up on your Ethnicity Estimate.
In other words, we can now see ethnicity inheritance data at the chromosome level on Ancestry and we will know which parent corresponds to each copy of the chromosome. This is a really big deal, and I am very excited to be able to use this tool.
Just like with the SideView, or Ethnicity Inheritance by parent results, we can see the Chromosome Painter information even if our parents have not tested their DNA. This is a huge benefit to those Ancestry users who have not been able to have their parents take a test.
As I have mentioned before in my writing about the SideView technology and how to understand your results, this is beneficial even to those of us who have had our parents or grandparents take tests to further our family tree research. With the Chromosome Painter tool, we will now be able to identify exactly through which lines of our tree we inherited specific DNA ethnicity regions.
Do you need an Ancestry subscription to see the Chromosome Painter?
In order to access your Ancestry Chromosome Painter results, you will need to have an active Ancestry subscription. This is one of a few features that have recently been added to the members-only Ancestry DNA experience.

How to find your Chromosome Painter results?
People who have tested their DNA with Ancestry will be able to log in to their Ancestry account and see their Chromosome Painter results on the SideView Ethnicity Inheritance section of their DNA Story. Since this feature just began rolling out on July 19, 2022, it might take a day or two for it to show up on all accounts.
On your Ethnicity Inheritance page, scroll down to view your Chromosome Painter results. It should appear just below the Ethnicity Estimate and Ethnicity Inheritance information.
On the next screen, you click on the “Chromosome Painter” beta tab to use the feature. If you don’t yet see it on your DNA kit results, it will probably show up within the next day or so.
There are currently three main functions of the tool. Conceivably, there will be more advanced features developed over time, but for now you can:
- Adjust the filter on your Ancestry Chromosome Painter to view only the specific ethnicity regions on the chromosomes where it is found
- Filter your results to only show one parent (i.e. Parent 1 or Parent 2)
- If you manage the results of more than one person, you can flip between test results directly from this screen, whereas you could not do so before
For example, I know that I inherited DNA matching the Jewish Peoples of Europe region from my mother. In fact, my SideView results helped me discover that this DNA was passed down from my maternal grandmother to my mother, and then to me.
However, with the new Chromosome Painter, I can now see exactly which DNA segments on my mother’s chromosomes actually match this region. You can see this for yourself in the image below:
To filter out only the DNA segments on my mother’s chromosomes that match the Jewish Peoples of Europe, I clicked on that region and then all of those segments were highlighted in purple. As you can see in the image above, my mother has segments of her DNA that match the Jewish Peoples of Europe on Chromosome 1, 3, 6, 10, 12, and 18.
I’m currently working on a series of posts that will include more about how to understand ethnicity inheritance on Ancestry, and a breakdown of how to understand the ethnicity inheritance on the Chromosome Painter to learn more about your family tree. When they are done, I will be sure to link to them here.
The Chromosome Painter is an exciting tool, but to understand what we are seeing when we use it, we do need to venture into the more intermediate genetic genealogy topics.
How to know who is Parent 1 and Parent 2 on Chromosome Painter?
While Ancestry’s software is able to figure out how to sort your chromosome copies into two groups (for your two parents), it is up to us to figure out which parent is our mother and father. Fortunately, many people will be able to easily make this determination by examining the main Ethnicity Inheritance, or SideView, results.
I describe how to do this in the link below. You will also be able to assign paternal and maternal labels to each parent to make understanding your Chromosome Painter results easier:
I hope that this post about the brand-new Ancestry Chromosome Painter has helped you understand how to find and interpret your results, and how to use this information to learn more about your ancestry on both your maternal and paternal lines.
It’s a really very exciting development, and we are only now able to begin learning how to fully leverage this new feature for genealogy.
If you have any questions about something that you read in this post, or if you would like to share something that you learned from using this feature, I would love to hear from you in the discussion below.
