UPDATES:

• December 2, 2018 Update from totheletterDNA (via their FB page) – there are 48 samples extracted and ready for genotyping. There are also 150 new samples undergoing extraction this coming week. All extracted samples will be genotyped before Christmas. Turnaround times should be improved moving forward due to having a “more streamlined process in place.”
• November 18, 2018 Update – DNA was found in every sample analyzed, with the oldest being from 1930. All samples are being run through a second extraction method at the Garvan Institute of Medical Research, after which there will be quality checks of the extraction. Samples that went through two extraction methods will be genotyped twice, once for each method/sample.

ORIGINAL ARTICLE:

Artifact testing promises to be an interesting component of the future DNA evidence and genealogy. If we can obtain and reliably identify DNA from deceased ancestors, relatives, or other individuals, we might be able to enrich our genealogical research.

For years I’ve been telling people that there is an enormous untapped market for artifact testing, and that they should hold on to their artifacts because a company will arise to offer this service. I typically follow that up by telling them NOT to literally “hold on to their artifacts” because I don’t want them to contaminate them! But seriously, there are many thousands, potentially millions, of artifacts that could possess DNA from long-dead individuals. ... Click to read more!

Many DNA test takers have a wealth of genetic relatives! For example, I have more than 50,000 different genetic cousins across all the genealogy DNA testing companies. Although many regions of the world do not yet have 1,000’s of genetic cousins in their match lists, they will in the future as DNA testing grows increasingly popular and the testing companies target other countries.

Unfortunately, the testing companies have not provided users with the tools necessary to organize these matches. Indeed, clustering and organization of genetic cousins is a huge component of the future of DNA evidence. Clustering of our matches allows us to identify information that is not visible or apparent when the matches are unorganized.

This is where the DNA Match Labeling extension for Chrome comes in! I worked with a programmer to build this extension. ... Click to read more!

AncestryDNA today (12 September 2018) released updated ethnicity estimates for all customers. Everyone in the AncestryDNA database will see some change in their estimate.

This update represents one of the most significant refinements of AncestryDNA’s ethnicity estimates. Both the reference populations and the ethnicity algorithm underwent significant development.

The size and makeup of the reference populations grew substantially, from ~3,000 reference samples to ~16,000 reference samples (many provided by test takers that consented to participating in AncestryDNA research). The update adds 17 new regions to the ethnicity analysis (from 363 to 380). Many more are needed in areas such as Asia and Africa, of course, but this is a great addition. As well, many regions were redefined or their names were changed to more accurately reflect the region. ... Click to read more!

DNA Central (www.DNA-Central.com), your one-stop resource for DNA education, has just gone live! See below for your special discount membership offer, a thanks for being a The Genetic Genealogist subscriber!

What is DNA Central?

There is an enormous need for DNA education. Millions of people are testing their DNA every year, but there are so few educational resources for those test takers. Receiving your results from the test company is just the first step in the process. How do you understand those test results? What do you do with them?

DNA Central is my effort to provide that DNA education in multiple formats. The membership-only website will provide resources for people at all levels trying to understand their results and stay on top of the most recent developments in DNA. These resources include: ... Click to read more!

Today (23 May 2018), the Board for Certification of Genealogists announced a 60-day public comment period for a set of proposed DNA standards:

The link for the Genealogy Standards is here: https://www.amazon.com/Genealogy-Fiftieth-Anniversary-Certification-Genealogists/dp/1630260185.

The PDF of the proposed standards is here: https://bcgcertification.org/DNA/Proposed_Standards.pdf.

Via a Facebook post, BCG announced the following:

The Trustees of the Board for Certification of Genealogists (BCG) met in Grand Rapids, Michigan on 2 May 2018. The trustees…debated a proposal to update genealogy standards to incorporate standards related to genetic genealogy. As a result of this discussion BCG intends to move forward with the integration of genetic genealogy into Genealogy Standards. The board directed that the committee’s proposal be published for public comment. The proposed standards can be viewed at https://bcgcertification.org/DNA/Proposed_Standards.pdf. The public comment period ends on 23 July 2018. Fill out the survey at this link (https://goo.gl/forms/57ahXLqkAYOBWDop2) by 23 July 2018. Due to the expected volume of comments, we will not be able to acknowledge or respond to individual comments. ... Click to read more!

Last year in the Facebook group Genetic Genealogy Tips & Techniques, we were discussing the need in the community for an informed consent agreement and a beneficiary designation form. Provided below are informed consent agreement and beneficiary designation form that I drafted with very helpful feedback from the GGT&T community early last summer. Feel free to use these agreements/forms pursuant to the disclaimers below, and pursuant to the CC license under which they are distributed!

Please note that this is NOT legal advice. I do NOT make any representation that these forms are legally binding or sufficient for their intended purpose. I highly recommend that you see an attorney if you have any questions or concerns.

DNA is hard. There’s no way around it. Sure, it’s easy to spit in a tube, but once you have all those percentages and centiMorgans and matches, how do you make sense of it? What does it all mean? And how can it help you understand where you came from and how to use it to explore your ancestry?

Announcing DNA Central, a new resource for everything DNA! This new subscription-based site will have blog posts about the latest and greatest, how-to content (including a  “What Next?” series), short videos (such as the “3-Minute DNA” series), webinars, and forums! We’ll also have monthly giveaways and much more! It’s everything you need to finally understand and apply the results of your DNA testing! ... Click to read more!

I started The Genetic Genealogist on February 12, 2007 with my first post, “New estimates for the arrival of the earliest Native Americans.” There were few educational resources for genetic genealogy back then, and all testing was Y-DNA and mtDNA. Although 23andMe would launch the first large-scale atDNA test a few months later in November of 2007 (see “23andMe Launches Their Personal Genome Service” announcing the $1,000 test), it would be a couple of years until they used the results for cousin matching. Today, almost 11 years later, there are 617 posts with more than 310,000 words.

Here’s a screenshot from the blog in December 2007:
