... Webinars. Tim gave an introductory talk and an advanced talk on the use of Autosomal DNA Testing. In both talks, Tim showed the well-known and often referred to Speed and Balding diagram which I’m showing here: It is also highlighted on the ISOGG Wiki Identical By Descent page, where it says: “A study by Speed and Balding (2015) using computer simulations going ...

... Annual International Conference on Genetic Genealogy held each year by Family Tree DNA and I’ll be going to Houston from November 10 to 12 to attend. This is a tough one to get into (unless you are a speaker) as registration is only open to FTDNA group administrators, which I am not. But when Bennett Greenspan attended my Double Match ...

... breakfast together, and then I led off repeating my talk from the day before on intro DNA. I had a few less people than the day before since many had already been at my first talk. It was again well received with many good questions. A few people met to talk to me one on one afterwards. My talk a bit later on using Autosomal DNA to help ...

... represented here, plus people from a number of States as well. My talk on intro DNA went well with good response and questions. I had anticipated many of the questions. To my recommendation that adoptees test everywhere was a suggestion that one should test at AncestryDNA because it has the largest number of testers and then transfer ...

... this morning, and how he and I would look to be half-sharing about a quarter of our DNA in a chromosome browser. Well that would make my grand-nephew the quarterback of my DNA Football team. His father, my nephew, would be the halfback. My daughters would be fullbacks. My sister would be in the 3/4 back position:  the ...

... talks on Acadians, Loyalists, immigration and Scotland. I’ll be giving 3 talks on DNA, 2 of which will be on DNA basics for genealogists and one a little more advanced on autosomal DNA analysis. I’m anxiously looking forward to the conference, meeting the other 11 speakers, and spending time with ...

... it may be possible one day for DMT to identify these for you. David Boyles on the DNA Tools Facebook group asked me to explain this more fully and I thought that was a good idea. The example diagram used in the documentation may not have been the best one to explain this concept because it didn’t have easily identifiable crossovers in it. So here’s a new ...

When I was first learning about autosomal DNA analysis, just over a year ago, I was under the misconception that if three people triangulate on a segment, then that segment is IBD (Identical by Descent). A segment that is IBD is one that is passed down from a common ancestor. These are the segments you are looking for. By ...

... late about 9:30 a.m. I heard the end of Shelley Talalay Dardashti talk describing DNA matching at MyHeritage: At10:30, I listened to Bennett Greenspan tell us about Family Tree DNA. My notes from his talk included him saying: “There will be some new tools coming out in the next quarter or two, like triangulation.” Also of ...

... Each will have slightly different sets of matches, different sets of people they’ve DNA tested, and interesting problems to overcome that I have not seen before. I look forward to hearing their questions, comments and suggestions and using this information to further develop Double Match Triangulator. I gave all the participants a 4 page handout with some preparatory ...
