Last night I released an update with several enhancements to the DNA Coverage tool that I’ll list in this short post.
The coverage estimator is a new tool at DNA Painter that lets you build a tree or import a GEDCOM and then mark the people in that tree who have tested. It then estimates the DNA coverage for the root person based on the testers. In this post I explain how to use it.
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.
The Library of Matches is a new tool by Cody Ely with example shared segments for different known matches. This visualization of segments could help you distinguish between different relationship possibilities.
I recently added focus mode, a new feature in WATO that I hope will help you.
Bucketing is a new DNA Painter tool that can help you subdivide your segments based on match or segment lists of other relatives.
Here’s a summary of new features at DNA Painter that I’ve released in the last couple of weeks.
I’m pleased to release a new tool today called the Shared cM Investigator. Intended for those who have siblings tested, but not the parents of those siblings, the tool uses segments and a simple mathematical equation to estimate how much DNA the parent of those siblings might have shared with the match.
I recently added a new feature to WATO following a user suggestion. Here is a quick update explaining how you can use this to find Y-DNA and mtDNA testers.
