A Review of TribeCode by Centrillion Biosciences

aSN0QmAV_400x400TribeCode (www.TribeCode.com) is a relatively new direct-to-consumer genetic genealogy testing company, officially launching in the fall of 2014. The company is owned by Centrillion Biosciences, headquartered in Palo Alto, California. The TribeCode test, currently offered for $99, offers Y-DNA, mtDNA, and atDNA analysis.

The ISOGG wiki page about TribeCode offers some information about the test, gleaned mostly from Facebook postings by the company. For example, the test apparently uses an Illumina low-coverage sequencing technology and tests at least 12 million markers throughout the genome. More exact details of the sequencing aren’t yet found on the TribeCode website.

Around Thanksgiving of 2014 I ordered the test on sale from approximately $79, and received my results a couple of months later.

An mtDNA Journey – Discovering My mtDNA in a Research Paper

I’ve always known that I have weird mtDNA. This morning, I learned that it is so weird that it has helped identify a new branch of the mtDNA Haplogroup A family tree.

Haplogroup A

When I first received the results of an mtDNA test ten years ago, I was shocked to learn that my mtDNA belonged to Haplogroup A, one of the well-known Native American haplogroups. I knew that my ancestors on my maternal line were British missionaries to Roatan, Bay Islands, Honduras, traceable back to about the 1820’s, and so I was expecting haplgroup H or another traditionally European mtDNA haplogroup.

My mtDNA Line – 5 Generations in Photographs

Not surprisingly, I had no close matches in the Family Tree DNA database. And when I tried to research my haplogroup, I had a handful of control region mutations that no one else in the database or the academic literature seems to have.

Creating DNA Circles – Exploring the Use of “Genetic Networks” in Genetic Genealogy

I recently forced the creation of a DNA Circle at AncestryDNA by target testing a descendant of a common ancestor. This blog post offers some information about how I did it, and some of my reasoning for doing so.

AncestryDNA’s DNA Circles

AncestryDNA offers a tool called DNA Circles, which is a group of at least three individuals that share a common ancestor in their public family tree at Ancestry, and each member shares DNA identical-by-descent with at least one other person in the circle.

According to AncestryDNA, a DNA Circle “open[s] the possibility for AncestryDNA members to identify distant relatives with whom they do not share DNA IBD directly, but with whom they still have genetic evidence supporting their relationship.” Instead of relying on just triangulation, DNA Circles rely on the concept of a Genetic Network.

Applying Autosomal DNA to Complex Genealogical Questions

800px-DNA_sequenceA new must-read piece of genealogical scholarship using autosomal DNA as evidence was published this week in the National Genealogical Society Quarterly, a publication of the National Genealogical Society. The article, authored by Thomas Jones, Ph.D. and entitled “Too Few Sources to Solve a Family Mystery? Some Greenfields in Central and Western New York” is one of a tiny handful that use DNA as one of several different pieces of evidence to answer a genealogical question.

While issues of the NGSQ are available only to members, gaining access to the benefits of NGS – including the NGSQ and the increasing number of articles incorporating DNA – is well worth the $65 membership fee.

The Shared cM Project – An Update

As you might recall, a few months ago I sent out a call (“Collecting Sharing Information for Known Relationships“) for information about the amount of DNA shared by people having a known genealogical relationship. I was hoping to get a better picture of the ranges of the amount of DNA shared by people in these relationships (through about the third cousin range). The incredibly generous genetic genealogy community responded by submitting data bout more than 6,000 relationships!

I posted information a few weeks ago (“Collecting Sharing Information for Known Relationships – Part II“), but today I have an update.
