Since late 2007, several “direct-to-consumer” or “DTC” genetic testing products have entered the marketplace, many of which offered some degree of autosomal ancestry analysis (including 23andMe, deCODEme, and Pathway Genomics, among others).
On May 6, 2010, the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany presented the world with a draft of the genome sequence of the Neanderthal (press release here (pdf) and full article here (free), NYT article here). As part of the announcement, the team presented their conclusion that 1% to 4% of the genome of non-Africans is derived from Neanderthals:
“An initial comparison of the two sequences has brought some exciting discoveries to light. Contrary to the assumption of many researchers, it would appear that some Neandertals and early modern humans interbred. According to the researchers’ calculations, between one and four percent of the DNA of many humans living today originate from the Neandertal. ‘Those of us who live outside Africa carry a little Neandertal DNA in us,’ says Svante Pääbo. Previous tests carried out on the DNA of Neandertal mitochondria, which represents just a tiny part of the whole genome, had not found any evidence of such interbreeding or ‘admixture.'”
New GeneTree Services Enable Users to Make Sense of Genetic, Genealogy Information
New GeneTree Products and Services Focus on Making Genetic, Family History Information Comprehensible and Meaningful to Users
As a wholly owned subsidiary of Sorenson Molecular Genealogy Foundation, GeneTree is able to Leverage the World’s Most Comprehensive Collection of Correlated Genetic and Genealogical Information on Behalf of Users
Re-Designed Web Site Includes Enhanced Content and Features
SALT LAKE CITY (March 31, 2010) – GeneTree today announced that the company has launched a new product offering of integrated genetic and genealogical services unique in the marketplace for its ability to expand users’ knowledge of their genetic and family history connections. The company also announced it has significantly revamped its Web site, www.genetree.com.
GeneTree’s comprehensive new service offering focuses on integrating two essential sources of human identity: quality genetic tests and industry-standard family history consulting services. In contrast to providers that focus exclusively on anthropological deep ancestry, GeneTree’s product and service offering is designed to help people discover near-term family connections in the last six to ten generations as well as deep ancestral connections.
Randy Seaver at Genea-Musings (â€œI’m Puzzled by DNA Claims on â€˜Faces of Americaâ€™â€) writes about the fourth and last episode of â€œFaces of America,â€ a PBS documentary series investigating the ancestry of several famous people in America. This fourth episode included several different types of genetic genealogy to examine the ancestral origins and relatedness of the showâ€™s members.
1. Whole Genome Sequencing by Knome
The first type of genetic genealogy was whole-genome sequencing by Knome of Henry Louis Gates and his father. This analysis examined Henryâ€™s (â€œSkipâ€™sâ€) genome for medical conditions and physical traits, and also compared his DNA to his fatherâ€™s, thereby allowing them to deduce the entire DNA contribution from his deceased mother. This segment was actually quite moving, as Dr. Gates was able to establish this intimate connection to the mother that he and his father obviously missed very much.
â€œEarlier this year, I submitted a saliva sample to Pathway to get a feel for how the latest consumer genomics offering compares to the more established companies in the field. Pathway communicates the health results not by a numerical relative or lifetime risk but via a series of color-coded bins depending on their potential significance to the individual.â€
I too recently had the opportunity to test my DNA through Pathway Genomics. (DISCLAIMER: Although this test kit was not free, I am a consultant for Pathway Genomics. This review, however, contains my own opinions of the Pathway Genomics Ancestry Test product). This is a brief review of the Pathway Genomics Ancestry Test, which examines SNPs on the mtDNA (for both males and females) and the Y-chromosome (for males). Using those results, Pathway classifies test-takers into one of over 1,200 maternal haplogroups and one of over 525 paternal haplogroups.
Late last fall, Family Tree Magazine requested nominations for the best genealogy blogs, and then opened voting for the nominated list.Â Yesterday, they announced the winners of the voting.Â Diane Haddad wrote about the announcement on the Genealogy Insider blog, and Maureen Taylor wrote the article that will appear in the May issue of Family Tree Magazine: “Fab Forty.”
I am very pleased and honored to announce that TGG was selected as one of the 40 Best Genealogy Blogs, in the category of genetic genealogy. I would like to thank everyone who nominated and voted for me.Â I have been very fortunate over the last few years to interact with a fascinating array of readers, and I am thankful for every one of them.
When I started blogging in February 2007 (I just recently counted my third anniversary of TGG!), there were very few blogs in the genetic genealogy space.Â Today there are a number of interesting and well-written genetic genealogy blogs.Â See my recent round-up at “10 Great Blogs for Genetic Genealogists.“Â Each of these blogs is well worth adding to your reading list.
In a move that puts it in more direct competition with personal genomics companies such as 23andMe and deCODEme, the genetic genealogy testing company Family Tree DNA announced today that it will offer a large-scale autosomal test for genealogicalÂ purposes.Â The test, which will be available to the public in mid-March, will allow test-takers the opportunity to connect with matching family members across all genetic ancestral lines.Â The test will launch at a price of $249.
Although other companies such as 23andMe and deCODEme offer similar tests, members of the genetic genealogy community have lamented the fact that their databases are populated in significant part by people who have no interest in genealogy.Â Presumably, people who purchase the FTDNA test and become part of that database will be strongly motivated by genealogical interests, and thus will be interested in communicating with genetic relatives.
First of all, you have to make sure you’ve got the free Firebug plug-in installed. Right click on the little bug in the lower-right corner of your browser window, and choose “Enable all panels”.Â Then left click the same bug icon, which should make a whole new section appear at the bottom of the screen.
Familybuilder, launched in 2007, is a genealogy company that ranks among the top 10 online genealogy services in the world with over 17 million users and over 120 million family tree profiles.Â Late last year the company began offering a genetic genealogy product, as I wrote about here on the blog (see â€œFamilybuilder Announces DNA Testingâ€).
Disclosure: This is a review of Familybuilderâ€™s Y-DNA service using a kit I received free of charge for purposes of this review.Â Please note that this is not meant to be an endorsement but merely a review of the Y-DNA service offered by Familybuilder.
The results of a Familybuilder Y-DNA test includes:
â€œThe Migration Map for you and your ancestors, your 17 Markers, your Haplogroup and the History of your DNA.Â In addition, the ability to share your results with family and friends on social networks such as Facebook and MySpace as well as a downloadable PDF (suitable for framing).â€
Linda Avey, co-founder of 23andMe, has started a new blog entitled The Life & Times of Lilly Mendel. I’m looking forward to some interesting reading as Linda establishes the Brainstorm Research Foundation dedicated to the study of Alzheimer’s disease.
