About this webinar

A genetic family tree is the list of genealogical ancestors from whom you inherited DNA. One of the goals of genetic genealogy is to recreate this genetic family tree through a process called “chromosome mapping.” Chromosome mapping uses cousin matches to identify which segments of DNA came from which ancestors, thus recreating your genetic family tree. We’ll look at the fundamentals of chromosome mapping and some tools you can use to begin to map your DNA.

    Is it really true you need to know how you know them? I was shown how to bulk map people out of My Heritage and knowing where we matched on chromosomes I recognised how we matched because they matched with other triangulated known group members. And so this gave me a clue to how these unknowns were related. Right?

    Good information about DNA Painter, I'm excited to try it.\n\ngreat\n\ngreat ….\n\nGreat graphics in the handout. Also took a very complex (for me) subject and was able to use small words to help me understand. I want to know more and Blaine just gave me the confidence to go forward.\n\nGreat information on chromosome mapping and DNA Painter.\n\nGreat information. Clearly stated.\n\nGreat intro to using DNA Painter!\n\nGreat learning experience ... thank you\n\nGreat overview of genetic Family tree and DNA Painter\n\nGreat subject and speaker. I always learn new skills with Blaine. Thanks.\n\nGreat topic, clear and precise presentation. Overall WELL DONE.\n\ngreat webinar\n\nGreat webinar - first time listening to Blaine \n\nGreat webinar on DNA\n\nGreat Webinar.\n\nGreat webinar.\n\nHave been thinking of trying DNA Painter and now I most definitely will! Excellent, clear presentation. I have Blaine's book on DNA and I found it the same--very easy to understand. A true gift!\n\nHe did a great job speaking to beginners in this topic. I will be watching it again to pick up more information. \n\nHe made it seem so simple. I feel like I can actually do this!\n\nHelped me to understand chromosome browsing and DNA painter better. Still a ways to go though.\n\nhelped me to understand chromosome mapping. excellent webinar\n\nHis webinars are always very interesting, each time I learn more about DNA.\n\nhopefully will learn more about dna\n\nHow-to demonstrations that walk through the process are so helpful. The pace of this webinar was also very good; I didn't have any trouble keeping up. Excellent presentation all around. Thank you!\n\nI had just looked at DNA Painter so this webinar came along at the perfect time and made so many points much clearer.\n\nI always learn so much from Blain. He can really explain DNA so that even I can understand it.\n\nI am finally understanding why could be helpful! Thank you!\n\nI am going to recommend this webinar to a distant cousin who is having a VERY difficult time understanding which ancestors he inherited DNA from and hope it will help him to make some sense of his matches.\n\nI am new to DNA analysis, so this webinar was a good starting class to learn some of the basics of DNA mapping. Some things were still hard to understand, and I have never tried DNA Painter, since so far my DNA is only on Ancestry, but \nit was informative.\n\nI can't wait to try painting!\n\nI enjoyed this because Blaine explained why DNA is so important AND how to best use it. Thank you.\n\nI felt this was presented at a level I could understand and WILL try. Thank You Blaine\n\nI had heard of DNA Painter but had not tried it. Now that Blaine explained it all I'm excited to try it out!\n\nI have a better understanding of chromosome mapping for the first time. Thank you Blaine Bettinger for a most fabulous webinar. You were clear, concise, interesting and your visuals were excellent!\n\nI have a much clearer understanding of the use of DNA for making matches. Thanks for making it simple enough for a beginner. \n\nI have ALWAYS been confused about how to use DNA. This is the FIRST explanation that made sense to me. It was just really very well explained. I will have to go back to listen again for reinforcement, but it's becoming clearer. I will \ndefinitely go back to hear some of his other presentations because this one was so good!\n\nI have been researching my ancestors looking at a combination of physical connections and DNA. My mother was adopted and though common connections through ancestry.com, I was able to determine by mothers father, but not her mother. This \nseminar was great in giving me information on what would be productive and what would be of limited or no value in my research. I have a half second cousin and was excited about the information that her DNA would give me. We have same \ngfather but different gmothers.\n\nI have been thinking of using DNA Painter, but was not sure the best way and was worried about starting off on the wrong foot. This was perfect for getting me going. Now I need to go through my list of correspondence to gather all my \nmatches that we have identified the MRCA.
