Reorder groups by dragging and dropping them using the grabber icon to the right of the name in the key

View segments in a particular group by clicking the group name in the key.

Click 'All segment data' to see a table of all your segments, which you can download and filter by keyword

Click on any chromosome number to expand that chromosome in place and see all the segments stacked

Everything is editable. Click on a segment to see more info, edit it, or view/edit the match or group

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!

new segments over (or with no cM value set) imported for ~ matches.

Note: If you retain the threshold and match names as imported, DNA Painter will automatically skip these matches when you next import the data. To force the importing of duplicates, uncheck the 'Skip matches that seem to have been imported already' option.

Family Finder import complete!

All groups with names beginning 'ftDNA' were checked, but no matching match names were found.

Some ftDNA matches have been moved to Maternal and/or Paternal ftDNA groups according to the information in the Family Finder matches file you uploaded. You'll see these groups at the bottom of the key on the right.
