Native American DNA by Roberta Estes – Favorite RootsTech 2020 Class

Apr 18, 2020

Many Americans have been told by relatives that they have Native American ancestry and want to find out if the story is accurate. DNA testing has the capability to help people determine if they inherited any DNA from Native American ancestors. At RootsTech 2020, I attended a class taught by DNA expert Roberta Estes entitled "Native American DNA: Confirming Those Stories." I am sharing some of the helpful information from Roberta's class and including links to her website, DNAeXplained, for more information. Her lecture was my favorite class from Rootstech 2020 because she has so much experience about this topic...

RLP 70 – DNA Tools and Methodology part 2: Chromosome browsers, segment triangulation, chromosome mapping, visual phasing

Nov 11, 2019

Today's episode of Research Like a Pro is a discussion with Robin Wirthlin about DNA tools and methods involving segment data. AncestryDNA doesn't provide segment data, but the other companies do! With chromosome browsers and segment data, you can use segment triangulation and chromosome mapping to prove common ancestors. Join us as we talk about how this all works!

Segment Triangulation: Proving an Ancestral Line

Aug 9, 2019

Have you heard the term "segment triangulation" associated with DNA and wondered what that meant? Perhaps you wondered if this could help you confirm an ancestor that you've researched? Which DNA testing and third party companies offer this tool? In this article, I'll define the term and show how the process can help you in your genealogy journey of discovering your genetic family tree. Pedigree Triangulation I previously wrote about pedigree triangulation and used the following visual from the ISOGG Wiki page to explain the concept. You and your DNA match both received DNA from your Most Common Recent Ancestor (MRCA)....

The Chromosome Browser: A Tool for Visualizing Segment Data

Aug 4, 2019

For most of us, the goal of genetic genealogy is to identify how our DNA matches are related to us. We want to determine our common ancestor or identify an ancestor who was previously unknown to us. Chromosome browsers help us do that. By determining that an autosomal DNA segment was inherited from a certain ancestor, we can use that segment information in the future to identify matches whose connection to us is unknown. Chromosome browsers also help us triangulate segments of DNA data shared with 2 or more genetic matches. When segment triangulation is achieved, we are able to...
