Chromosome mapping is typically achieved by mapping the segments of DNA we share with an identified match. In this lecture, learn how to map segments of DNA that you DO NOT share with a match! Using close relatives such as parents or siblings we can figure out where pieces of DNA came from based on lack of sharing.

Blaine makes it sound so easy. He is clear and concise. Great presentation.
Blaine was so easy to follow, learnt a lot, just sad that I do not have a sibling/parent/uncle/aunt I can have tested.
Blaine, as usual, explained a potentially confusing topic in an extremely easy and digestible fashion. I will definitely be using deductive chromosome mapping in the future, probably tonight!

Extremely interesting
Fabulous!
Fabulous! Thanks Blaine. Excellent, clear explanations as usual!
Fantastic session. Blaine has a gift for making things east to understand.
Fantastic webinar!
Fantastic! I just wish I had siblings willing to test and share.
Fantastic. Definitely advanced, and glad that this was explained at the start.
fascinating!
Fascinating. My sister has also tested (Ancestry) and I will have to get her to upload to GEDmatch so I can try this out. Thank you!
Fascinating. Look forward to trying out the new learning. Thank you.
For an “Advanced” webinar there was a lot of basic training
Glad to see the complete focus on deductive mapping — Michelle included it in her talk (as inferred mapping) and did a good job on it, but it really needed a fully dedicated webinar — if I am not mistaken, Louis Kessler (who won best innovation at RootsTech a few years ago) was the “inventor” of this
Good audio, well presented
Great info so far but this is more advanced than my knowledge right now.
GREAT INFO!
Great info! I wish he showed a parent for deductive mapping!
Great information…easy to understand.
Great lecture and so easy to understand. Thank you.
great material
Great presentation. Presented in a way that was easy to understand.
Great slides.
Great topic. The speaker was very detailed so that everyone would understand the process.
Great webinar as always. Thanks for organising Geoff.
Great!
He explained it very well.
He really does good explanations so I learn more and more about DNA.
His presentation made me want to try the DNA printer program and also use the Deductive mapping with cousins to find out more information about our shared grandfather.
I always enjoy Blaine’s talks and explanations about DNA!
I always learn a ton from Blaine’s lectures, but I have to say that this one tonight really blew my mind! I’m so excited to get my siblings tested and try this methodology out! Thank you –
I always learn something new from Blaine!
I couldn’t stay for the whole webinar, but what I heard was great! Thanks for making it available at a good time for us in Australia.
I don’t think of myself as an advanced dna user but decided to take the webinar anyway in hopes I might pick up something. Mr. Bettinger explained the process so systematically and logically, I’m excited to get started on my own chromosone painting.
I enjoyed the webinar and it clarified mapping. Thank you so much.
I feel like I discovered another piece to a puzzle. Great job of explaining it.
I had to stop watching after about half an hour, but the webinar looks like just what I need to help me maximize what I can learn from having tested other family members. I’m looking forward to finishing the webinar once it’s in the archives. Thank you, Blaine!
I know now that I need more relatives to do their DNA to check for matches and differences.
I learn a little more with every webinar. DNA and chromosomes are hard for me to grasp.
I missed a few minutes in the beginning, but overall very good! Thank you, Lisa
I really enjoyed the examples showing application of using this Deductive Chromosome Mapping technique. Thanks!
I watched knowing that I, as an only child with no living parents or first cousins that will test, would not be able to use this technique. However, I GET it- and maybe I’ll be able to help others in my genealogy group use it. Blaine is always an excellent presenter- he knows how to break a subject down and keep adding just a bit more so you really can understand. By the end, a complex topic is now understandable.
I would give it a higher rating if possible. Excellent!
I’d rate him a 10 if I could!
I’m actually just still starting with DNA, but I still learned a lot in terms of the windows that DNA mapping can open. Fabulous class – everything so thoroughly explained that even I grasped the concepts! Thank you!
In-depth, knowledgeable, with lots of presentation materials to break it down which made it comprehensible.
Interesting info and presented very well.
Is there any way I can give this webinar a rating of 10?
It is interesting that for DNA Painter, Jonny says not to use siblings; however, that is exactly what you need for this type of chromosome mapping. Very interesting to think there is often more information than we know right in front of us.
It is time-consuming to state things clearly, but glad Blaine does it that way.
It makes perfect sense what Blaine explained. I’ve worked with DNA painter a bit but am unsure on how it will move my search for ancestors forward
It was a very good presentation and Blaine explains it so well. The suggestion to draw it out will help to prevent confusion. I’m eager to try this!
It was great to have a webinar on advanced DNA techniques.
It was great. Can’t wait to try what was taught!
It was indeed a light bulb moment. Thanks, Blaine.
It was very helpful to me. The description could have mentioned that it is useful only when you are certain of the relationship of the match.
I’ve done Visual Phasing so this was great to see how to actually use the Deductive process. I’ve thought I could do it but now know how to do it properly. Thanks Blaine for another exremely well explained and clearly demonstrated process to add to my DNA kit!
I’ve had a eureka moment or two during this webinar. Blaine at his finest.
I’ve heard the concept, but it was a good visual to help with the explanation.
just great, thank you
Looking forward to more DNA webinars on the Advanced Level!
Lots more to learn
Love getting taught by Blaine. He is one of my favorite presenters, and this explanation of Chromosome Mapping was excellent. Thanks Blaine.
Love those light-bulb moments! Thanks!
Loved the advanced level of utilizing DNA
Makes use of those black spaces that I never thought about before. Thanks, Blaine.
mind blown! great info…keep it coming!
Most helpful webinar on DNA I’ve ever watched. Can’t wait to test my sister!!
My mind was blown! Blaine Bettinger makes a complicated process feel so simple! He gives me hope that I can use my DNA matches to figure out my great grandmother’s side of my family tree!
Never a disappointment with Blaine Bettinger!
New advanced technique, well explained by Blaine.
Now I have a name for something I’ve been doing for a long time. I’m a very logical person though so I figured it out on my own.
One of the best !
One of the best on Genetic Genealogy I’ve seen, ever. So glad I’ll be able to view it again, as a (long time) Legacy Webinar subscriber. Thanks to both Legacy Webinars and Blaine T Bettinger.
One of the best webminar I had here yet! Thanks to Blaine!
Organized, logical and to the point. I was waiting for someone to explain relationships and mapping your grandparents dan using your siblings. Thank you Blaine”
Outstanding session!!!
Outstanding!!
Outstanding!!!!!
Really enjoy Blaine’s presentations.
Really enjoyed this, thank you!
Really nice to remember to watch one live. This year is my 3rd year for membership. It is such a benefit- I cant always make a conference – but I can learn new things with the webinars.
Received valuable information for my research. Thank you!
Simple – not to broad a subject like some are. I could understand the concept as it was explained in detail.
Simple and easy to understand. Thanks!
Simple, clear, concise explanation of deductive mapping with two examples… loved it!
So clear. Blaine made a difficult subject easy to understand.
So pleased I was on holidays and could view very useful.
So well done. Even tho’ I haven’t spent a lot of time on chromosome mapping, Blaine did such a good job explaining his deductive mapping, that I was able to understand it easily. Thank you!
Speaker kept his presentation simple and too the point.
Stupendous presentation-clear and concise!
Succinct, concise, and clear! A great way to break down an advanced topic!
Such a complex topic but Blaine explained it so clearly. Tomorrow I will give it a try!
Super
Super and I actually understood it.
Superb—need more like this.
superstar with great information and presentation!
Terrific!!
Thank you- very informative!
Thank you!
Thanks Blaine for a wonderful webinar. As usual, you explain even difficult topics with amazing clarity. I’ve been trying to get my head around this topic for ages, but now I feel confident that I finally understand it! Can’t wait to start mapping deductively!!
Thanks Blaine. Awesome webinar – very clear. You make a complex topic understandable. Thanks Legacy for providing these webinars!
The concept of deductive chromosome mapping finally makes sense to me. Thank you, Blaine B!
This is amazing stuff! And Blaine, as always, explained it so well.
This was a lightbulb moment for me!
This was a very good intro to deductive chromosome mapping. I would like to know applications of how to use this info and also to know if you can use the info to expand/broaden beyond one generation? Thanks!
This was great!
This was great. Very clear and informative.
This webinar may help me to finally differentiate dna between my deceased parents that I was unable to test. As usual, Blaine has demystyfied DNA so a lay person can better understand. Thanks Blaine and thank you Legacy Webinars for continuing to bring great educational programs for better research techniques.
This webinar was very enlightening and informative. Very, very helpful in comparing sibling & cousin DNA differences. Blaine explained the process in a way that was easy to comprehend.
top notch
unbelievable good!
Unfortunately came in just at the end–looking forward to the replay tomorrow! Good night, everyone!
Very clear and concise. I actually followed!! I’m anxious to try it on my own.

Very clear, step through. Only additional information I would like would be using a match to a second cousin.
Very clear, thank you!
Very clearly explained as usual.
Very clearly presented!
Very clearly spoken, and each piece of information was clearly explained before moving on. Excellent presenter.
Very detailed and this about my 4th webinar about this subject
Very easy to follow.
Very good and useful info but presentation was overly repetitive.
Very good explanation. Easy to follow.
Very good information we will be able to use. Thank you!
Very good, clear instruction. Liked it a lot!
Very good, Would appreciate a bit more depth. Would enjoy a webinar with both visual phasing and deductive mapping used concurrently and cross referenced. It was just a tiny bit slow going. So 4.5 would be my real rating.
Very helpful! Thanks!
Very illluminating!
Very informative and helpful. Thank you!
Very informative and I got it totally. Can’t wait to apply it.
Very informative with easy to understand examples – Thank you!

Very interesting…. perhaps a little advanced for me but definitely added to my understanding of utilization of DNA matches
Very precise examples and the speed at which Blaine spoke made it an informative session
Very stimulating presentation, great to have my understanding of this subject clarified, thanks, Blaine.
Very Understandable
Very useful although I am still at beginner stage
very useful technique very well explained

Wasn’t as advanced as I expected, having already done visual phasing,
Watched this because of Blaine!!
We always get better insight into DNA from Dr. Bettinger. And he makes it so easy to understand. Thank you very much.
Well explained – I’ve found a new way to occupy hours of my day
Well presented and easy to understand. Thank you!
well presented!
What a fantastic step forward — it is great that an advanced session is being presented in clear terms but without having to cover basics.
What I enjoy about Blaine’s webinars is that he doesn’t teach at the lowest common denominator level. He is brilliant, what else is there to say?
Wonderful
wonderful and Blaine’s explanations are clear and easily understood
Wonderful information!
Wonderful, wonderful webinar of using Deductive Chromosome Mapping. The light did come on for me also.
Wow! Anxious to get started!
Wow, I learned a lot!
Wow. Just wish my parents and siblings were alive to collect DNA from so I could map them
