You may have wondered, “What are DNA SNPs, and how do they help us find our ancestors?” Sometimes it feels like a strange new world when you venture into using DNA in your family history research. Some terms may be new to you, and it’s a challenge to absorb all of the new information and keep up with technological advances in the world of genetic genealogy. I made a new video explaining SNPs – which are...
Have you ever used the MyHeritage chromosome browser to view triangulated segments? It’s a wonderful tool. A member of the Research Like a Pro with DNA study group asked a great question about his experience using it. He said, I’ve compared the DNA of 3 people with my mom: Bob, my mom’s 1st cousin on her dad’s side two DNA cousins I’m researching, Jane and Jill (names changed) Bob triangulates with Jane on chromosome...
Segments of DNA that reportedly match can sometimes be pseudosegments, or false segments. These pseudosegments were not inherited from a common ancestor. In this Research Like a Pro with DNA Q&A video, I discuss pseudosegments and share an example of finding a probable pseudosegment with a match at MyHeritage. When creating triangulated groups with MyHeritage matches following Jim Bartlett’s methodology, you can sort overlapping segments into two groups, one for maternal and one for paternal....
X-DNA has a unique inheritance pattern, and knowing about it can sometimes help you figure out the ancestors you share with a DNA match. Men inherit a Y chromosome from their father, and an X chromosome from their mother. It is easy to imagine that an X chromosome remains unchanged just like a Y chromosome does when it is passed from father to son, but this is not the case with X-DNA. Here is a...
Have you wondered how to create a citation from microfilm reels that you ordered from an archive or library? A Research Like a Pro with DNA Study Group member asked the following question. I had sent for microfilm records from the Library of Virginia (LVA) through their inter-library lending program and printed out pages and pages of these vital records. I kept all of the documentation, correspondence with the lending library I used, and documentation...
Today we have the following question from a Research Like a Pro with DNA study group member: If you already know the relationship to a match, is there any other reason to contact that match? Yes, there are many reasons to contact your DNA matches, from verifying their tree, to asking them to share their matches with you. As you establish communication with them, it opens the door for further collaboration. When you need to...
Today I am answering a new question for our Research Like a Pro with DNA Q&A series: “Should I sort my 23andMe matches by percent or strength of relationship?” The RLP with DNA study group member asked this question during assignment 1, which includes sorting DNA matches into color clusters using the Leeds Method. The full question is: How does 23&Me determine “Strength of Relationship?” Is this a more valuable sorting mechanism to use for...
We are starting a new series called Research Like a Pro with DNA Q&A. Study group and eCourse members ask questions, and we answer them with a short video. Today, the question is: “what is the significance of the first cluster in an AutoCluster or Collins Leeds Method chart?” I answer the question by showing an example of a MyHeritage AutoCluster chart where the clusters are ordered by size (number of matches in the...
