Following the release of the AncestryDNA Chromosome Painter, I thought it would be interesting to compare the offering of each company that now offers segment data for their ancestral composition (aka “ethnicity”) estimates. My family’s estimates are probably more interesting than they will be for those who have fewer different ancestries in their background. You

Earlier in July 2022, AncestryDNA launched a new feature: Chromosome Painter. In this post I’ll introduce a new tool that allows you to extract segment data that you can use to paint population information in your DNA Painter chromosome map.
Painting your populations
As well as mapping DNA segments to ancestors, you can also map your population segments at DNA Painter. In this post, I explain how to do this and how it can help you investigate and confirm other matches.
Bucketing is a new DNA Painter tool that can help you subdivide your segments based on match or segment lists of other relatives.
Geneanet recently launched some enhancements to their DNA tools. Here I explain how you can bulk import Geneanet segment data into DNA Painter.
For my second guest post, I’m pleased to welcome Rachel King, a professional genealogist based in London, England. Here, Rachel shares some examples demonstrating how she uses segment data in her work.
Here’s a summary of new features at DNA Painter that I’ve released in the last couple of weeks.
For this first guest post, I’m pleased to welcome Lara Diamond, whose popular blog Lara’s Jewnealogy has been running since 2013. Endogamy has a very visible effect on chromosome mapping, as Lara explains very clearly
As part of your ongoing DNA work, you might sometimes like to merge chromosome maps together or use data from one map in another. In this post I recap on the different ways you can duplicate and copy data between chromosome maps.
Distinct segment generator
As announced last month in the newsletter, the new distinct segment generator tool allows you to amalgamate a set of segments that more than one family member shares with a specific match. The tool will then output just the distinct segments, with the centimorgans (cMs) recalculated.
