    Great information. I had already read Blaine Bettinger’s book, Guide to DNA Testing and Genetic Genealogy. The webinar helped me gain a better understanding of what information each type of DNA testing will provide. Especially the explanation of the genetic distance markers.

    As a beginner genealogist I’m so thankful for this updated series and will sure come in use with my DNA analysis of autosomal matches of my ancestral lines.

    The presenter had an invaluable power point and was clear in his explanations. I’m sure that questions on Mt DNA and Y DNA will be answered before the end of this series. I would love a new series showing step-by-step how he found his missing second great-grandmother using Autosomal DNA. Lots of the DNA detective tv shows skip too many steps on their discoveries.

    He gave me a good foundation to understand the basics of DNA. I expect to be able to use this knowledge to improve my understanding as we go through the remaining four courses.

    Blaine has such a great way of explaining DNA – whether you’re just starting out or have been doing this for a while like I have. He makes the complicated information makes sense! His teaching style is unique, and I can’t wait for the next webinar in the series.
