I finally DNA-tested my children and got the results recently. This has been fascinating and I’m sure I’ll be writing more about it in the coming months. While working to interpret their tests, I’ve created the common segment generator.
I’m pleased to present some recent DNA Painter updates. I hope these small tweaks enhance your experience on the site.
This post outlines how I recently evaluated shared segments when investigating a new DNA match. I also considered the conclusions I can draw by comparing the new match with other close relatives who have tested.
I have worked with computers almost every day since I started working in 1995. I’m aware that this isn’t the case for everyone, and that I inevitably have a tendency to gloss over certain technical details when explaining DNA Painter to people. This article is an attempt to correct this, with a guide to every step involved in mapping a match onto your chromosome map.
In this follow-up article I discuss inferred chromosome mapping in more detail, also introducing a new tool I’ve created to make the process easier.
Chromosome mapping has a dedicated following, but it might not be for everyone. So why map your chromosomes? In this article I’ll attempt to explain it concisely so you can figure out if it’s worth your time.
Since DNA Painter first launched in 2017, lots of new features have been added. Some longstanding features are also quite well hidden! My thanks go out to everyone who has made recommendations. Here is quick run-through of some features you might have missed within chromosome maps.
This article first appeared on the Medium website but has been moved to this blog… Chromosome mapping is the process of using the data from matches to assign segments of your chromosomes to specific ancestors — from grandparents to more distant forebears. DNA Painter is a simple web-based tool for chromosome mapping that I built
