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!

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

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...

  • When my mom got the suitcase of unorganized genealogy papers from her dad, she tackled organizing by doing a quick sort into Grandpa's four main lines. #genealogy #organization #familyhistory #byuedweek
  • My Grandpa on a fishing trip in northern California circa 1950. #genealogyphotoaday day 19 - My Grandpa
  • My mother, Diana, and I love creating educational content. One of our favorite creations in the last two years has been our Research Like A Pro brand. Our weekly Research Like A Pro podcast has grown significantly since we started and we are grateful to all our listeners! This photo was taken at the BYU conference on genealogy and family history a couple weeks ago next to our booth in the vendor hall. #genealogyphotoaday day 14 "my creation" #genealogy #familyhistory @dianaselder
  • My hometown is Seattle, Washington. This is me at age 8 with my family in West Seattle. #genealogyphotoaday day 10, my hometown
  • My grandmother, Nan, in the 1950s, before tragedy struck her life. She was a cheerleader and a tomboy. She married her high school sweetheart, Warren. They had little baby boy. Soon after this photo, Warren was diagnosed with pancreatic cancer and passed away. I look at this picture and think about the difficult times that were ahead for my grandmother. What an awful shock that must have been to become a widow so suddenly. She later met and married my grandfather, Bob. I'm so grateful she overcame the heartbreak of losing her first husband and took another chance on love and marriage. #genealogyphotoaday August Day 9, my grandmother #familyhistory #savefamilyphotos
