The day has arrived! Version 4 of the Shared cM project is now out, and there’s an updated shared cM tool as well. Since 2015, Blaine Bettinger has been crowd-sourcing data on the number of centimorgans (cMs) of DNA shared for known relationships. The result is an incredibly useful dataset that helps genealogists start to
A quick post to announce two updates to DNA Painter trees. These include mitoYDNA.org integration and the ability to view your tree with additional display options. Display options Under the settings cog/gear on the right there are now a number of display options. These give you the ability to view additional information within the tree
DNA Painter is known for chromosome mapping, but also includes ancestral trees, a useful interface for visualizing your family line (aka pedigree). To create your ancestral tree, you can select your GEDCOM file and have DNA Painter extract your direct line. Or if you prefer, you can enter it manually. Trees are private by default
Since I first launched DNA Painter, I’ve had a steady stream of requests to include the locations of traits within chromosome maps. Last month I finally implemented this after a dream in which I did just that! Background I find when I try to explain chromosome mapping to non-genealogists, they often ask tricky questions. Such
In exactly one week’s time I’ll be in Salt Lake City for Rootstech. It will be the second time DNA Painter has exhibited. A lot has changed since 2018, when my newly created company was awarded a booth within ‘Innovation Alley’ as part of the DNA Innovation contest. This year, I’m looking forward to demonstrating
I’ve made a new page listing upcoming and previous lectures, webinars and exhibitions.
Next up for me is a lecture in my home town of Belfast for Genetic Genealogy Ireland on February 15th.
I realize lots of people have now tried Cluster Auto Painter (CAP), and not all of them will have experience of chromosome mapping or DNA Painter. Here I show the mechanics of how to use DNA Painter to annotate and investigate your clusters, including assigning them to your maternal or paternal side.
I’m pleased to introduce Cluster Auto Painter (CAP), an early step towards automated chromosome mapping. CAP aims to help you dig deeper into your DNA test results by letting you annotate and examine your clusters in a chromosome map.
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
