DNA Testing -- A gift for everyone

Isn't this the year you decide to give everyone in the family a DNA test? Capture their DNA now so you and future generations can benefit from knowing more about your family history than through any other means. As Dr. Spencer Wells once said, "The greatest history book ever written is the one hidden in our DNA."

Family Tree DNA, the company that founded the industry and that continues to lead as it offers a full array of DNA tests for genealogy, once again has launched its Holiday Sale. Take advantage of these great prices for new tests and upgrades to existing tests. (Just a reminder: Family Finder is equivalent to the test offered by Ancestry, 23andMe, and MyHeritage.)

Living DNA - One-World Project

Living DNA, a testing company based in England, originally focused on the British Isles and offers very interesting insight into the genetic makeup of that part of the world. It has now expanded into Germany to conduct aa similar study. It has launched a One-World Project and now invites anyone who has tested with other companies (Ancestry, 23andMe, Family Tree DNA, etc.) to upload their raw data to its database for free.

For more information, see Debbie Cruwys' blog.

Notice: It does not yet offer a matching service but has promised to add this in the future.

More about the Triangulator

Correction: You are not limited to 5 names. If your ICW list for any individual contains 30 or fewer people, you can simply select ICW, then DNAged Tools, then Triangulator to process all of them. If you want to process all except close relatives, for example, click the box next to all except the close relatives.

Exciting new triangulation tool

FamilyTreeDNA.com has incorporated a new tool that should help all of us in the quest to analyze matches. (If you did not test at FTDNA, you can "transfer" your raw data from wherever you did test to FTDNA's Family Finder, and also to Gedmatch.)

Learn about the new tool here: https://dna-explained.com/2017/10/21/introducing-the-triangulator/.  To access it, first open your Chrome browser, click on More Tools, then Extensions, then choose DNA Genealogy Exp[eriment Loader. That activates it. Then open FTDNA Family Finder, click the box to the left of any match, click on In Common With. Start at the top of the list, click the first 5 names, then click on dnagen tools, then on Triangulator.

Will imputation help or hinder?

DNA testing for genealogy is at risk. Only Family Tree DNA has resisted using the newest chip offered by Illumina, the only viable company making such chips for autosomal testing.


The new chip is comparable to the old in only 20% of coverage! The companies using it are now forced to apply “imputation”, a means of inferring results. I find that shocking and a severe blow to the efficacy of genetic genealogy.  For a detailed discussion, see  https://dna-explained.com/2017/09/05/concepts-imputation/
