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.
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.
Launched in late 2020, the inferred segments generator helps users calculate the segments they can infer from the DNA their close relatives share with others. This can be a confusing concept. I recently added a small additional feature to the tool that can help you infer segments from a grandparent.
An interesting DNA match to my mother-in-law Lynn* and her maternal aunt (Ann) appeared this week. In this article I’ll review how I interpreted their match with Tom alongside methods for interpreting inferred segments when working with a full aunt: What can I infer about Lynn’s DNA from the segments her aunt Ann shares with
