Overview: With a single mouse-click sophisticated genetic tests for human ancestry analysis are available directly to consumers at a relatively low cost. Advances in human genetics over the past 30 years have enabled the emergence and growth of this “recreational genetics” marketplace. My goal is to introduce the science underlying these tests, compare the products delivered by the companies that dominate the US marketplace (e.g., 23andMe, AncestryDNA, Family Tree DNA, MyHeritageDNA, and The Genographic Project), and demonstrate their utility. Personal genetic analysis provides a window into the past at different time scales, including genetic inferences of pre-genealogical ancestry along with the discovery of genetic relationships between cousins as a genealogical research tool. They also provide the means to glean information from your own DNA recipe.
- Evaluate the products and deliverables of direct-to-consumer DNA tests
- Conceptualize the organization of the human genome and properties that contribute to its variability among individuals
- Build proficiency in the methods and interpretation of test results of human ancestry and biological relationships
I posted a few times in the summer of 2015 when 23andMe and AncestryDNA both reached the threshold of genotyping their first million customers. I'm consistently amazed at how popular these commercial DNA tests have become. In this year, 23andMe has grown to 2 million customers in the 10 years https://mediacenter.23andme.com/about-us/ since launching the first version of their DNA testing service. AncestryDNA now has 5 million customers https://www.ancestry.…
October 23, 6-7pm, Digital Media Lab, 2nd Floor, Iowa City Public Library
AncestryDNA provides an intuitive web interface for navigating the results of a DNA test, which has fostered their growth to now having more than 10 million customers. A variety of features available on the AncestryDNA platform are not obvious and may not be apparent to the casual user. This meeting of the DNA Interest Group will focus on accessing these hidden features and using them in family history research. We will meet in the Digital Media Lab of the Iowa City Public Library. Attendees are encouraged to bring a device for accessing their AncestryDNA results or bring their login information and access their account using a computer in the library. This presentation will also provide insights and applications for those that have not taken the AncestryDNA test but may be considering it.
