Chromosome Mapping Helper for DNA Painter is a Chrome extension that copies chromosome segment data from MyHeritage DNA match pages straight to your clipboard, ready to paste into DNA Painter.
How to use it
- On the MyHeritage DNA match page, scroll to the bottom so the chromosome browser loads fully.
- Click Capture & Copy Segments in the side panel.
- In DNA Painter, open your chromosome map, choose Paint a new match and paste.
What it does not do
The extension doesn’t give you access to anything more than you already have on MyHeritage or DNA Painter. It only takes data your browser has already downloaded and simplifies moving it from one place to the other.
