Chromosome mapping is a technique for comparing your DNA with others to identify the ancestors who passed particular segments of DNA to you. This information can then help identify where any new ‘matches’ fit within your tree.

Chromosome mapping is an emerging technique that increases the benefits of DNA testing. It is likely to become a key tool for genealogists.

This guide helps you through the steps from downloading your DNA from the different testing companies and finding shared segments as well as identifying the ancestors who handed it down to you.

Once identified, the  segments can be added to a chromosome map, labelled with the name of the ancestor from whom you inherited it as well as the genetic cousin whose DNA allowed you to identify it. 

Coverage includes  two methods of recording the data and displaying  a chromosome map:

  • DNA Painter – a dedicated online program into which you paste segment data, and
  • Kitty Cooper’s Chromosome Mapper – receives input from a spreadsheet of shared segment data.
