Today’s episode of Research Like a Pro is about the new DNA tools at LivingDNA. Initially, we discuss our personal projects and thoughts on time management, emphasizing the importance of prioritizing life goals and projects. We then shift to the main topic: our experience with LivingDNA’s new tools, specifically the chromosome browser and the Matchbox. We explain how these tools help in organizing DNA match lists and provide insights into ancestral connections. LivingDNA’s unique feature...
Today’s episode of Research Like a Pro is about the Coverage Estimator tool at DNA Painter. We discuss the purpose of the tool, some ways to use it, and how to use it. We also share some examples of how we’ve used it. Nicole shares her Joanna West case and how the coverage estimator showed increased coverage as more test-takers were added. Diana shares how she is using the coverage estimator to track the coverage...
Today’s episode of Research Like a Pro is about the second half of Chapter 8 in Research Like a Pro with DNA. This part of the chapter focuses on tools that use segment data to help you find common ancestors with your matches. We discuss chromosome browsers, segment triangulation, chromosome mapping, DNA Painter, visual phasing, and several third party tools. We also review tools to help analyze mitochondrial DNA, Y-DNA, and X-DNA matches. Transcript Nicole...
When you hear the term endogamy, what communities come to mind? French Canadians, Puerto Ricians, Mennonites, Pacific Islanders, and Ashkenazi Jews are common examples. Some of these examples are from island peoples, so what about the Irish? Last time, I discussed the effect of a clearly endogamous community, Ashkenazi Jewish (AJ), on a relatively non-endogamous community, German, within my dad’s match list. My dad has more AJ matches with longer segments (greater than 20 cM),...
Can segment patterns help you differentiate matches with paternal grandparent from a maternal grandparent? A tool at DNA Painter helps you do just that. The tool is called Library of Matches – https://dnapainter.com/tools/lom, developed by Cody Ely. In a blog post titled “Introducing the Library of Matches,” from May 2022, Cody shares how he came up with the tool. He was working on an unknown parentage case and was trying to determine if a 333...
Today’s episode of Research Like a Pro is about double cousins. Do you have any? We’ll talk about how double cousins and other relatives with whom you share multiple relationships can affect DNA match analysis and genetic network analysis. Although double 3rd cousins don’t always share an inflated amount of DNA, you can definitely tell they are double cousins in your network analysis. Join us as we discuss these issues. Transcript Nicole (1s): This...
Do you have DNA matches that seem to belong in multiple genetic networks? Are you nervous that you’re seeing pedigree collapse or endogamy? Before you despair, realize that this phenomenon could be due to DNA matches sharing more than one common ancestral couple with each other, or what’s often called “multiple relationships.” In Diana’s post, Endogamy, Pedigree Collapse, and Multiple Relationships: What’s the Difference and Why Does it Matter, she talked briefly about multiple relationships...
