Tomorrow night at 7 PM EST, I will give a live webinar demonstrating some of the basics of DNA testing for ancestry, including many different ways you can use DNA to solve your family mysteries. The cost is $49.99, which includes the hour-long webinar and my presentation slides. This is the second DNA webinar I’ve given for Family Tree University, and the last one was very well received. It is better suited for those who are new to DNA testing or have received their results and are unsure how to apply them.
And if you are unable to attend tomorrow night, you can download the video and slides at any time! I hope to see you there!

I know I say this every year, but 2014 is shaping up to be the year of Genetic Genealogy. There are many incredible opportunities this year for anyone interested in genetic genealogy to learn more and interact with others.
For example, just last month RootsTech 2014 featured numerous DNA sessions. This coming June, there will be an entire day of DNA at the 2014 SCGS Jamboree, where I and many other speakers will cover numerous topics related to DNA (see my coverage here and here). Among my presentations at Jamboree will be a completely new lecture that I’m really excited about – “DNA and the Genealogical Proof Standard,” which will be the first presentation completely devoted to the topic, and which I hope will spur some important conversation!
And in July 2014, Debbie Parker Wayne, CeCe Moore, and I will be teaching “Practical Genetic Genealogy” at the Genealogical Research Institute of Pittsburgh (GRIP). This will be the … Click to read more!
The Southern California Genealogical Society has officially announced the 45th Annual Southern California Genealogy Jamboree (June 6-8, 2014), which will again be preceded by Family History and DNA: Genetic Genealogy in 2014.
Last year’s “Family History and DNA: Genetic Genealogy in 2013″ was the first of its kind and was a huge success As a result, the Jamboree organizers have organized a second DNA Day, which will held all day on Thursday, June 5, 2014, which is the day before Jamboree begins.
The FULL schedule for DNA Day 2014 is HERE (Thursday Schedule).
Keynote Speaker Dr. Maurice Gleeson
The keynote speaker at Family History and DNA: Genetic Genealogy in 2014 will be Dr. Maurice Gleeson, a popular speaker and the organizer of Genetic Genealogy Ireland 2013, Ireland’s first conference on genetic genealogy. I had the opportunity to speak with Dr. Gleeson at last year’s event (including about his … Click to read more!
Understanding the complexities of autosomal DNA can be very challenging for newbies.
However, there are a few basic tenets that I believe can help these newbies. These tenets are essentially tools that newbies can use to analyze an autosomal DNA problem for themselves.
For example, here are the two very basic tenets that I typically introduce in my autosomal DNA lectures especially for the newbies:
- You only have to go back about 5 generations to start losing ancestors from your Genetic Family Tree.
So many of the issues that newbies run into can be resolved or prevented through understanding of these concepts.
The Coop Lab
The lab of Graham Coop, an associate professor in the Department of Evolution and Ecology at UC Davis, maintains a blog where they often discuss genetics. Today they published an interesting blog post … Click to read more!
23andMe and Udacity today announced a new online course entitled “Tales from the Genome: Adventures in DNA, Identity, and Health,” a Massive Open Online Course (“MOOC”) directed at genetics. According to the website, students will learn about “fundamental principles of inheritance, gene expression, mutation and variation, development of simple and complex biological traits, human ancestry and evolution, and the acquisition of personal genetic information.” The class is labeled as being aimed at beginners.
Although not announced on the Udacity website, the course will be available beginning on September 30, 2013.
The “Tales from the Genome” class will be taught by Matthew Cook, Lauren Castellano, Joanna Mountain (of 23andMe), and Uta Francke (also of 23andMe). For more information, see the press release at Market … Click to read more!
At Salon, an article entitled “The college class that could reveal your real father” by Katya Cengel discusses a course at Stanford called “Genetics 210.” The class uses [entirely optional] 23andme testing to explore the many issues associated with genetic testing. Although the class is offered to both graduate and undergraduate students, the class is filled with mostly graduate students.
All students go through the informed consent process carefully, and have access to a genetic counselor and a psychiatrist (although according to the report not a single student has contacted the psychiatrist in the four semesters the course has been offered, and only two have contacted the genetic counselor).
The most interesting aspect of the article, to me, was the complication that identical twins … Click to read more!
I’ve received a number of emails and comments (see, e.g., here) complaining about Ancestry.com’s new test, AncestryDNA. Specifically, several test-takers believe that the Genetic Ethnicity Prediction provided by Ancestry.com does not reflect the numbers that they expected based on their own research.
“I just got my DNA test results back from Ancestry.com and I am concerned. I was born in England and I have gone back many generations and have found that all my ancestors as far back as the 1600′s in most cases are English. According to the results I have no British Isles DNA. It states that I have 60% Central Europe, 30% Scandinavian and 7% Southern Europe. I also have 3% unknown. How can this be?”
“Just received my results: 21% Southern European and 79% Central European which doesn’t follow years of work on my family history.”
Do these comments reflect errors in AncestryDNA’s Genetic Ethnicity Prediction, or are there other factors at play?
Although I am not privy to the ‘behind-the-scenes’ at Ancestry.com, I don’t believe that there are serious issues with AncestryDNA’s Genetic Ethnicity Prediction. Ancestry.com’s DNA arm has a solid scientific team and a large and valuable reference database.
Indeed, Ancestry.com is well aware of the limitations and challenges that their Genetic Ethnicity … Click to read more!
As I’ve stated many, many times in the past, the future of genetic genealogy is combining test results with both family trees and paper records.
Today, MyHeritage and Family Tree DNA announced a partnership that will bring that future one step closer to reality. MyHeritage will offer a full line of tests (13 in total) through FTDNA, including these basic introductory tests (with discounts – not shown below – for MyHeritage subscribers):
- Y-DNA12 (12 Y-STR markers) – $99
- mtDNA (HVR1 region) – $99
- Family Finder (autosomal test) – $298
The FAQ page for the tests is here (and I note that although they currently do not allow import of test results from other providers, they plan to in the future). I wonder if existing FTDNA test-takers can import their results?
Given MyHeritage’s worldwide reach and enormous membership (62 million members around … Click to read more!
Last week I wrote about the results of my Family Finder autosomal DNA test by Family Tree DNA (see “A Review of Family Tree DNA’s Family Finder – Part I“). The Family Finder test uses a whole-genome SNP scan to find stretches of DNA shared by two individuals, thus identifying your genetic cousins (and will soon include the Population Finder analysis of admixture percentages). I currently have over 33 genetic cousins in Family Finder, and I’m working with them to identify our common ancestor(s).
The Affymetrix microarray chip used by FTDNA includes over 500,000 pairs of SNPs located on the X chromosome and the autosomes (no Y chromosome SNPs). Via SNPedia:
FamilyTreeDNA uses an Affymetrix Axiom CEU microarray chip with 3,269 SNPs removed (563,800 SNPs reported) for autosomal and X (but not Y or mitochondrial) ancestry testing for $289. Other sources have cited 548011 snps. This platform tests 1871 of the 12442 snps in SNPedia.
FTDNA states that the Family Finder test is not intended to be medical. From the FTDNA FAQ:
Question: Is the Family Finder test medical?
Answer: No, it is not.
This is entirely accurate of course; FTDNA does not analyze the test results for health, traits, or other medically-relevant … Click to read more!
Today at noon, the American Society of Human Genetics lifted an embargo on “Inferring Genetic Ancestry: Opportunities, Challenges, and Implications (pdf),” which will be published in the May 14th issue of the American Journal of Human Genetics.
This paper is a follow-up to a 2008 paper called the “ASHG Ancestry Testing Statement and Recommendations” in which a committee from the ASHG addressed concerns about the claims made by genetic ancestry testing companies. I wrote an article here on the blog at the time – The ASHG Ancestry Testing Statement and Recommendations – that highlighted a number of concerns I had about the statement and the recommendations.
When I wrote the November 13, 2008 blog post, I began by pointing out my personal positions, which have largely remained unchanged in the intervening 1.5 years:
- After years of experience in this field, I am a proponent of genetic genealogy testing, a scientific endeavor that has been utilized by more than 800,000 customers.
- I believe that education, not more government regulation, is the most efficient and appropriate answer to the issues raised by the authors of the paper.
- I believe that autosomal genetic genealogy testing is in its infancy and should only be used with the understanding that the results are only extremely rough estimates that are subject to change as the field develops.
The 2010 paper begins with a brief introduction and a table of most of the companies currently … Click to read more!
