Chromosome Painter - Detailed Segment View Guide

The Chromosome Painter Detailed Segment view displays your chromosome painting results in a table. This table allows you to sort your result data in ascending or descending order for column.

Accessing the Detailed Segment View

To access the Detailed Segment view: 

In the upper-left corner of the Chromosome Painter, click the Detailed Segment tab.

Detailed Super Population and Continent Views 

On the Detailed Segment view, you can select to view your results by Super Populations or by Contentinental Regions.

What are Continental Regions and Super Populations? 

Continental Regions are the main regions of the world in which one or more Super Populations are located.

Super Populations are populations found within each Continental Region. 

Click here for a complete list of our Continental Regions and Super Populations. 

Switching between Super Population and Continent Views 

To switch back Super Population and Continent views: 

In the upper-left corner of the Chromosome Painter Detailed Segment view, click Super Population or Continent to view your results by Super Population or Continent-level population, respectively.

Understanding Populations Sidebar 

The populations sidebar is dispayed on the left side of the Detailed Segments view. Here your Continental Regions, Super Populations, and Population Clusters are displayed as follows: 

  • Continental Region and the percentage of your autosomal DNA that corresponds with each of your Continental Regions. 
  • Your Super Populations within the corresponding Continental Region and the percentage of your autosomal DNA that corresponds with each of your Super Populations. 
  • Your Population Clusters within the corresponding Super Populations. 

Super Population View Sidebar Example

The following example shows a section of the sidebar with the Super Population view selected. Note that the Super Population has the color-coded dot preceding it. See the following Colorcoding section for more information.

In the image below, Europe = Continental Region, Western Europe = Super Population, and England, Wales, and Scotland and Scandinavia are Population Clusters.

Continent View Sidebar Example

The following example shows a section of the sidebar with the Continent view selected. Note that the Continental Region has the color-coded dot preceding it. See the following Colorcoding section for more information.

In the image below, Europe = Continental Region, Western Europe = Super Population, and England, Wales, and Scotland and Scandinavia are Population Clusters.

Super Population/Continental Region Colorcoding 

Super Populations or Continental Regions are colorcoded depending on which viewing option you select. 

If you select to view your results by Super Populations, you will see a color-coded dot beside the names of the Super Populations in the left sidebar and the same colorcoding for corresponding Super Populations in the results table. 

If you select to view your results by Continent, you will see a color-coded dot beside the names of the Continental Regions in the left sidebar and the same colorcoding for corresponding Continental Regions in the results table.

Understanding Detailed Segment Results 

On the Detailed Segment view, your chromosome painting results are displayed in a table.

This table contains the following columns: 

Super Population/Continental Region 

Dependinging on whether you selected to display your results by Super Population or Contient, the first column displays either Super Population or Continental Region, respectivel. 

Super Population 

The Super Populations in which one or more of your Population Clusters for which you have autosomal DNA results are found. This may also illustrate relatedness among the Population Clusters in this region.

Continental Region

The main region of the world in which one or more of your Super Populations for which you have autosomal DNA results are located.

Chromosome

Displays the chromosome pair (out of 22 autosomes) where the estimated population segment is located. A segment cannot cross chromosomal boundaries. These chromosome pairs are numbered 1 through 22. 

Haplotype

Displays the haplotype for which your results correspond. A haplotype is one of your two copies of a chromosome. Adjacent segments from the same population are sorted together into the same haplotype (1 or 2).

Start Position 

Displays the position on the indicated chromosome where the estimated population segment begins. This is based on build 37 of the human reference genome.

End Position 

Displays the position on the indicated chromosome where the estimated population segment ends, This is based on build 37 of the human reference genome.

Centimorgans (cM)

Displays the unit of genetic linkage for the estimated population segment. Segments inherited from more recent ancestors usually have higher values

Filtering Detailed Segment Results

The Chromosome Painter filter allows you to filter your results by specific Super Population(s) or Continental Region(s). 

To filter your results: 

  1. In the upper-left corner of the Chromosome Painter Detailed Segment view, click Filter. The filter menu is displayed on the right side of your screen. 
    Note: The top Chromosome View section Portrait View and Landscape View options are only for use when you are viewing your results in the Chromosome Painting view. 
  2. In the Preference section, click one of the following:
    Super Population - Select to display and filter your results by Super Population(s). 
    Continent - Select to display and filter your results by Continental Region(s). 
  3. Below the Preference section your Super Populations or Continental Regions are displayed depending on which option you selected in step 2. 
    In this section, select the Super Populations or Continental Regions for which you want to filter your results. 
  4. In the Trace Results section, select the Show Trace Results Only check box to view only your trace results. 
  5. Click Done. Your results are filtered per the options you have selected. 

Downloading Segment Information

To download a CVS file of your segment information, click the Download Segments button in the upper-right corner of the Detailed Segment view. 

Trace Results 

What are Trace Results? 

A Trace Result indicates that you have a very small amount of shared DNA in common with the corresponding reference population. Please note that smaller DNA segments are more likely to be misattributed.

Why do I have a Trace Result?

Although we have, through scientific research, autosomal DNA information for reference populations around the world, our algorithm is unable to assign this one small section of your DNA to a specific reference population for one of the following reasons:

  • Due to the broad scope of genetic diversity among humans, this one section of DNA matches multiple reference populations.
  • Due to the fact that scientists have yet to determine DNA information for all populations and regions of the world, this one section of DNA does not match any reference population.

As more DNA and scientific information is provided in the future, we will be able to enhance our algorithm and determine the geographic regions and genetic populations for Trace Results.
