About this webinar

Autosomal DNA tests are utilized in genetic genealogy to solve historic research questions by exploring the genetic traces left by deceased ancestors in the genomes of their living descendants. Any given descendant only inherits a portion of their ancestor’s DNA, and different descendants inherit different portions of that DNA. Based on the relationships between tested descendants of a research subject, it is possible to estimate how much of an ancestor’s DNA is represented in any given database. This information can help in prioritization of testing candidates and can also aid in interpretation of shared DNA between multiple groups of individuals.

    Excellent webinar. I learned a lot and can’t wait to try! Not a big fan of math, but enjoy the DNA equations. Totallhy makes sense.

    Thank you!

    FINALLY someone gave visual examples to the DNA concepts! Paul’s webinar is fantastic and easy to follow, but will definitely need to be rewatched for the practice at hand understandings. He is a great presenter!

    Amazingingly helpful. Will need to watch slowly and often to make all of this info mine. What a wonderful 12-page syllabus! I printed it on both sides and numbered the pages quickly; they, too, are going to get a lot of use!

    Pretty complex/advanced stuff. I will have to listen again after I read the handout and try the exercises he included. I think this will be a very useful tool.

    This was really great! I’m pretty knowledgeable about DNA, and I learned something today! I’m looking forward to studying the syllabus and watching this again.

    Gave me hope that I can figure out how DNA works. And hopefully, find out who my grandfather was.
