Library of MatchesUnspecified~ Maternal: ~ Paternal: ~ painted
Welcome! This is a map by Cody Ely, a genetic genealogist, featuring real examples of matches from a wide variety of relationships. You can use this to help predict your relationship to unknown matches, or as a resource to learn more about different relationships by seeing the shared segments. All matches have been genealogically verified by Cody, who will continue to add matches and manage the Library as time goes on. For more about Cody, please like and follow his Facebook page at facebook.com/codyelygenealogy
Instructions
- Each group in the key on the right is a set of shared segments between two people with a known relationship (a 'match'). You can find the known relationship (e.g. Paternal Half Siblings) in the group name.
- Use the key to find matches that are similar to your unknown match, or to find examples of a specific relationship type you are interested in seeing. The key is sorted by shared cM.
- If you like, click 'NONE' on the key to hide all of the matches, then click on the appropriate colored square to the left of the match you are interested in to make it visible.
- Search the key at the bottom right by typing the relationship abbreviation into the 'Search groups' field. For example, type '1C1R' for first cousins once removed.
- Matches in the key with the same letter in parenthesis can be displayed at the same time to visualize recombination and other helpful simulations.
- Grandparent and great-grandparent matches without a SNP count have been inferred, but are nonetheless accurate.
- Whether your matches are paternal or maternal does not affect the validity of using this tool.
However, please note that example grandparent and half sibling matches have been specifically labeled as paternal or maternal.
- According to Cody and others, these relationships have different segment patterns depending on if they are paternal or maternal.
- While you will share different segments and different amounts of DNA with your matches, this library of examples will hopefully help you in your research.
The process of painting a match involves some copying and pasting of data. While you can do this on a touch device, you might prefer to use a desktop browser!
Create a new chromosome map
A new chromosome map is a set of blank chromosomes that represent an individual who has taken an autosomal DNA test.
When you have a DNA match, you will match on particular segments. The aim of this site is to provide a platform that lets you take this match segment data and use it to 'paint' your chromosomes (or those of the person who took the DNA test!), adding as much information as possible so that you can use this info to help trace future matches.
You can choose whichever colours you like. For known connections, it can be a good idea to assign a distinct colour to each of the four grandparents, and then use variations of these. For more information on how to set up a chromosome map, click the Settings cog at the top left and then click on 'Tour of this page'.
Y and mitochondrial DNA
This map has the sex of the test taker set to 'Unspecified'. If you would like to restrict display of the Y-chromosome according to sex, please set this as male or female by clicking on unspecified to the right of the name at the top left of the page.

Help with this page
Welcome. Here's an overview of some of the features of the chromosome map page.
Advanced features
- Mass edit mode If you expand a chromosome or go into the group or match view, you can turn this on. It will then let you draw a box or click on segments to select them (hold down CTRL/CMD to select multiple segments) and choose a group/create a new group to move them to.
- Improved bulk imports Bulk imports from 23andme now take account of the Maternal/Paternal buckets, and there is an enhanced interface for the ftDNA maternal/paternal bucket tool allowing you to sort your matches
- More detailed match list The 'All matches' report under 'reports' now lists the total cM, number of segments, and average cM shared.
- Improved navigation The match overlay now includes a navigation link to get back to where you were (for example, if you click on a match name in the All matches report, the match overlay will contain a link back to All matches.
Controls
At the top left of your profile, just above the first chromosome pair, you'll see three buttons.
When you hover over a button, a tooltip appears explaining what it does. Click a button to expand/contract the chromosomes, view settings, or perform a search.
Expand/contract all
- The '+' icon expands all your chromosomes at once.
- After you click this button, it will transform into a '-' that you can click in order to minimize them again. You can still expand and contract chromosomes individually.
- After you expand all chromosomes, match names will show automatically. You can toggle this using the checkbox that appears above each expanded chromosome.
Search by match name
Your chromosome map has an auto-complete search.
- Start typing a match name, and matching names will appear in a dropdown
- Click a name in the dropdown
- All segments will be paled out and the matching segments will be highlighted. The first matching segment will have hover state expanded.
- Click 'clear' or the 'X' icon on the search panel to clear the search and restore the segments to their normal state.
Settings
Here you'll find actions:
- Share, Duplicate, Download a picture of this profile, Take a tour of this page, Import ancestry composition from 23andme, All segment data
In addition, the following features are available:
- Actions: Import data (for subscribers only; see below), import 23andme ancestry composition data, reset key position
- Options: Show match names in the group overlay, Show centromeres on chromosomes, Show keylines on expanded chromosomes, Hide unknown groups, Hide ancestry composition groups
- Reports: All matches, All segment data
Any options you select will be saved in your browser's local storage and will persist until you reset your browser or empty its cache.
Import Function
As well as adding individual matches, you can bulk import your match segments from a comma-separated-values (CSV) file.
The CSV file can be directly from your testing company (e.g. the CSV file of segment data provided by MyHeritage, FamilyTreeDNA or 23andme) or custom file (a template is provided in the import overlay).
This opens up a number of possibilities:
- Bulk import of all matches from a testing company in order to view patterns and chromosome coverage
- Adjust the thresholds for minimum and maximum cM values in order to import specific ranges
- Assemble profiles offline and import directly into DNA Painter
- Restore exported DNA Painter profiles
Please note: to use the import functionality, you need to subscriber.
Match detail
You can reach the match overlay view by clicking on any segment and clicking 'view match', by hovering over the match name in the 'All segment data' overlay, or by clicking on the match name in the group overlay and clicking 'view or edit match'.
Here you can:
- Click a button to copy all segments for this match to the clipboard
- A list of all matches who appear to share DNA with this match based the data you've entered
- A switch allowing you to view all overlapping segments within the match overlay
- The switch and list of matches will only appear if there are overlapping segments
New functionality
- Multiple segment deletion. In the 'all segment data' view, you can click 'mark for deletion', and a column will appear with checkboxes. There's also a checkbox in the table header to select all visible segments. You can use this to filter the table for the things you want to delete and then select them all. Once you click 'Delete segments', the site will say how many segments you are deleting and remind you that this a
