MyHeritage is the one main DNA company I have not done DNA with yet. I'm still getting used to 23andMe, and will soon have Living DNA to figure out, and am tapped out on learning new DNA companies for the year! Maybe next year.
But this webinar, Advanced Autosomal DNA Techniques used in Genetic Genealogy, originally presented in Israel by Tim Janzen for MyHeritage One-Day Genealogy Seminar on October 29, 2017, is a great way to see how to apply advanced techniques in DNA analysis (regardless of which company you use, I think):
This presentation will introduce some advanced techniques used by genetic genealogists including the use of triangulated groups, chromosome mapping, visual phasing, and phasing. Triangulated groups are clusters of matches who all share the same DNA segment and therefore all descend from a common ancestor. All serious genetic genealogists organize their matches into triangulated groups and then look for the shared ancestor common to everyone in each triangulated group. Chromosome mapping is the process of determining which portions of your DNA came from which ancestors and/or which geographic region or population. Chromosome mapping is essential to genetic genealogists. It allows you to focus your attention on a portion of your pedigree chart when you search for a shared ancestor with a match who shares a segment of DNA with you that you have mapped to a specific ancestor. Visual phasing is a powerful technique that helps you refine your chromosome maps if you have autosomal DNA test results from 3 or more siblings.
