About this webinar

Can I find out if I have Native American or African heritage by taking a DNA test? Why does my test say I have an ancestral origin that is not present in my pedigree chart? Why are places I know are in my family history missing from my chart? Why do I have different results than my siblings? How accurate are the results? Do small percentages matter? There are actually four factors that can help explain the results you see from our DNA testing companies, so come get some answers!

    I always enjoy webinars with Diahan because her passion and knowledge of the subject totally lock me in ! Thanks!

    I always learn something new and that is most enjoyable. Thank you.

    I always learn something new from Diahan Southard. I plan on listening to this Webinar again as I want to know which DNA testing companies will offer me what I’m looking for. I’d like to know how GEDMatch does their matches since they have people who test with different companies. I’ll save that question for Diahan’s Webinar in September.

    I always love learning from Diahan. She has so much to teach.

    I am a geneticist (PhD Biology) and genealogist for 60 years. Your talk was very good and accurate.

    I appreciate how Diahan Southard always makes complicated explanations understandable.

    I have stopped looking at my ethnicity report but I was wrong. What an eye opener to look again. Thank you, great, great lesson!

    I learned a lot from her clear teaching and diagrams.

    I love Diahan.

    I love Diahan; she always gives a great presentation and makes difficult subjects easy and fun!

    I love the way Dianah Southard explains DNA ethnicity results to the unscientific minded. Her graphics and analogies are very helpful.

    I loved understanding better how to use family groups and why some ethnicity doesn’t show up in my cousin’s DNA. Thank you!

    I missed the first half so need to go back and see the whole thing. It was very interesting.

    I need 70 more years!!! So little time, so many nifty things to test, research, etc.!

    I need to find out more about DNA

    I never understood about the algorhythms before. She did a great job explaining that.

    I never want to miss a presentation by Diahan Southard!

    I really enjoyed the presentation but it was so quick I will need to watch it again. Lots of information to digest. Thank you.

    I really enjoyed the webinar. Diahne is the best teacher

    I will have to watch it again to be able to think about each of the 4 factors.

    informative

    Informative and interesting

    Interesting ways to explain concepts that can be jargon-laden.

    It was very eye opening.

    it was very informative

    It was very interesting! She was a good teacher!

    just getting into looking closely at our DNA results and this was a great beginning

    Learn a lot

    Learned a great deal.

    learned a lot that I’ve never heard before!

    Learned a lot!! Excellent presentation!

    Learned more specifics about certain aspects of the DNA evaluation process and some additional things to chack out! Great job!

    Learning from an expert!

    Learnt so much from this webinar. A very clear and precise speaker.

    Looking forward to more.

    Love her examples. She always helps me gain a better understanding & shows me possible next steps to use the information.

    Love her pace, the analogies, handout ‘art’, and enthusiasm.. My background in math and science is minimal (thanks California experimental education) so I’m starting from the very basics. I’m also pleased that her sessions are recorded so I can re-listen. She gives so much information.

    Love listening to Diana. Always makes learning fun!

    Love the way Diane teaches. It makes a complicated topic easier to understand

    Loved it! I always learn so much from Diahan.

    Loved the presenter’s enthusiasm and analogies to help us better understand the science behind DNA matching.

    Makes it so easy to understand DNA

    My favorite presenter with always something new to take away!

    My understanding of how my DNA is determined has been beautiifully answered. Thanks

    need more

    Nice job or presenting – easy to understand. thanks

    Nice quick pacing. Informative.

    nice to know the factors considered in judging ethnicity

    Obvious expert in DNA methodology. Glad to hear AncestryDNA ranked so high and understanding my results which have changed over time presumably because of larger population groups or refined algorithms. Will need to review prsentation again to better understand nuances.

    One of my favorite speakers

    presenter was very enthusiastic and clear in visuals and explanations of a complex topic

    Pretty basic, but did provide some useful information.

    Prior to this webinar, I only knew Ancestry announcing that they were updating their ethnicity results. Now I must check the others.

    really good. wanted more about native american dna

    Really interesting. Learned lots. Thank you.

    Recall and Precision a bit confusing

    She always does a great job. Makes a complex issue understandable.

    She explains everything so clearly Thank you

    She has a command of the topic and presented the information in a logical sequence. She is obviously prepared in her presentation. Kudos.

    She is always excellent!

    She is always fantastic. Please have her more often.

    She is always so perky and so easy to understand. It is a pleasure, not a chore, to listen to her explain things.

    She is always so prepared and presents her material so clearly. Outstanding speaker.

    She was great! Easy to listen to and very interesting.

    She’s good!

    Simple, direct presentation from knowledgable presentor.

    So informative. I’ve learned so much. Thank you!

    So much help with the basis of the science of DNA brought to us in an entertaining and understandable way.

    So much new info for me. I will revisit this in the library.

    Still trying to understand all of this.

    Such a relatable speaker, it was easy to understand complicated concepts because she explains them so well and her analogies are great.

    Super teacher!!!

    Super Webinar

    Thank you for the information. Clear presentation. It would have been nice to expand on how each company reports their results and what they mean. There was a quick mention about how MyHeritage gives you a description of where your matches are from but that was it.
    Thank you!

    Thanks for making so many “”areas”” clearer. But I’m still baffled about some things.

    The comparisons of the various DNA companies was very interesting and informative.

    the enthusiasm of the presenter was infectious.

    The graphics are great!

    The information was very general and well presented. I’m looking forward, however, to going to the free link that Diahan gave to next-steps to flush the info out even more. I have to think about what I learned today. I’m pleased that she’ll be back in September to answer questions.

    This really helped explain ethnicity percentages.

    This was a great explanation of a complicated subject! I now understand what I’m looking at in my ethnicity results! Thank you!

    This was another great webinar! Thank you!

    This was excellent. I have DNA results from two companies that list the same places of origin but with wildly different percentages. This lecture was SO helpful in understanding how that could happen. Thanks!

    This was very interesting and easy to understand.

    This webinar gave me a start to some of my questions after being tested with two different companies. The Graphics were very helpful and I appreciated the simple way a topic was explained so that it was not so scary.
