The International Society of Genetic Genealogy (ISOGG) has just launched a new newsletter. The first edition, March 2008, is available here. This edition discusses GINA, a DNA Success Story by Shoshone, a segment called “The Armchair Geneticist: Where Hobby Produces Science”, What’s New in ISOGG, and a Featured DNA Project.
The newsletter is well-written and has some great graphics, so be sure to subscribe to this FREE newsletter (see the bottom of the newsletter for subscription … Click to read more!
I often get emails from people who are new to genetic genealogy asking questions about their newly-received DNA testing results. They are unsure about about what the results mean, how to find more information, or what to do next. I also see people ask these questions in all of the DNA forums and mailing lists that I subscribe to. Although I do my best to help the people that email me, I often wish there was more I could do.
In an attempt to assist people with the interpretation of their genetic genealogy testing results, I’ve written an eBook that takes the reader step-by-step through an analysis of their Y-DNA or mtDNA results, including estimating a haplogroup and sub-clade from testing results, finding resources to learn more about particular … Click to read more!
With the popular African American Lives series on PBS and numerous news stories and magazine columns, Black History Month often results in increased attention to the genealogy and genetic history of African Americans. I saw a similar increased interest in genetic genealogy last February as well.
The Multiracial Roots of Americans
Diverse has an article entitled “More Americans Are Discovering Their Multiracial Roots.” The article discusses traditional genealogical research, then mentions genetic genealogy – particularly automosal testing:
“One of the more fascinating developments with the new genealogy is the extent to which DNA testing is revealing the multi-racial ancestry of Americans. While thereâ€™s some controversy about the claims of DNA testing firms as to how accurately they can match individuals to ancestors from specific communities and ethnic groups, thereâ€™s a consensus that proper testing can roughly specify a personâ€™s relative mix of his or her ancestorsâ€™ geographic origins.”
The Pursuit of Happyness
Another great article is in Medill Reports, “DNA Traces African Past.” Christopher Gardner, the real-life story behind “The Pursuit of Happyness,” was recently given the results of an mtDNA analysis and genealogical study by African Ancestry. According to the analysis, Gardner’s mtDNA likely … Click to read more!
As I was reading through the GENEALOGY-DNA list from Rootsweb this morning, I came across a great question about the frequency of mutation of mitochondrial DNA (mtDNA).
The listmember asks “I am wondering if anyone would know the odds of having a mutation between my brother and me in our mtDNA. Marker 16163 is G for one of us and A for the other…” This is a great question, and one that I’ve been asked as well.
In response, Ann Turner writes “The mutation rate hasn’t been studied in the detail I’d like to see. The largest study for the hypervariable regions was based on deep-rooting pedigrees from Iceland. They found 3 mutations out of 705 transmission events.”
The study, available here (pdf, HT: Ann Turner) was conducted through deCODE Genetics and Oxford … Click to read more!
Although the world of genetic genealogy has slowed from the furor of November and December 2007, there is still plenty of discussion and consideration going on around the blogosphere.
First, Ann Turner , co-author of “Trace Your Roots With DNA” and moderator founder of the terrific Genealogy-DNA list has experimented with both deCODEme and 23andMe. Although she is still analyzing the results, she has a short write-up of deCODEme’s graphic presentations for comparing genomes (Word document here). The deCODEme comparison tool allows users to compare the degree of similarity between genomes, as long as the user has permission to compare. For those without a permissible genome to compare to, deCODEme provides reference samples from about 50 different populations. Ann points out that “it would be really interesting to hear if anybody is testing a number of close … Click to read more!
Genealogists spend many of their days (and much of their money!) tracking the history of their ancestors. They hunt through ancient records to elucidate even the smallest clue as to some facet of their ancestors’ lives. Since the majority of genetic genealogists started their journey as traditional genealogists, it is only natural that they enjoy record-keeping and tracking as well.
The DNA Genealogy Timeline is a free public resource maintained by Georgia K. Bopp and hosted by rootsweb.com. The timeline attempts to track the significant developments associated with genetic genealogy. It begins with “Before 1980″ and was updated most recently as of October 2007.
What immediately stands out is that genetic genealogy has been around much longer than people realize, especially given … Click to read more!
If you’re thinking about jumping into the field of genetic testing (whether for genetic genealogy or any other form of genetic test), you should be sure to do some research first. The results of any genetic test are incredibly personal, and can potentially have a huge impact. As a result, the decision to undergo testing should only be made after doing some vital research.
Luckily, a fellow DNA Network blogger has written a post that will help you do this important pre-testing research. Hsien at Eye on DNA has written “How to Prepare Yourself for a Genetic Test.” Hsien provides the following advice:
“Although you canâ€™t change your DNA, it is possible to prep yourself for a DNA test just as itâ€™s possible to prep yourself for a driving test. It is critically … Click to read more!
I honestly don’t know what to do with this next article. Meredith F. Small Ph.D., an anthropologist at Cornell University, wrote a brief article at LiveScience entitled “DNA Kits: Secrets of Your Past or Scientific Scam?” Dr. Small’s article is largely a comment on the article that appeared earlier this fall in Science, “The Science and Business of Genetic Ancestry Testing” (I provided an analysis of the article here at TGG).
According to Dr. Small:
“[The quest for identity] also leads unwary seekers of the past right into the hands of scam artists who claim they can trace anyone’s DNA back to its source.”
The sentence is extremely misleading:
First – a scam artist is by definition a person who engages in a “fraudulent business scheme.” Although genetic genealogy can be controversial, I’ve never heard a single customer accuse a company of running a scam. To the best of my knowledge, these testing companies are using the best science available to test DNA and compare results to their databases. Are physicians running a scam … Click to read more!

In Part I and Part II of the â€œYou and the $1000 Genomeâ€ series we examined the history of the Archon X PRIZE for Genomics and the success of the International HapMap Project. Today weâ€™ll talk about some of the ethical issues associated with efficient and inexpensive genome sequencing. The value of whole genome sequencing will only be realized if individuals believe they have complete and legal control over their genetic information. I am greatly indebted to a thorough analysis of this issue by John A. Robertson at the University of Texas School of Law … Click to read more!

In Part I of the â€œYou and the $1000 Genomeâ€ series we examined the Archon X PRIZE for Genomics, a $10 million purse for the group that can sequence 100 genomes in 10 days for no more than $10,000/genome with an error rate below 0.001%. With todayâ€™s technology this goal is still a few years away.
But do we need an entire genomic sequence to obtain all the relevant medical information that our DNA contains? After all, 99.9% of my DNA is exactly the same as everyone elseâ€™s! Why sequence that 99.9% over and over and over if … Click to read more!
