Genetics for Genealogy
This page provides a platform to organize and distribute workshop and course materials on the genetics of genealogical relationships. Here you will find slide presentations from past events along with links to web pages containing detailed explanations of certain topics.

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.…

In the past decade there has been an explosion of studies surveying genetic risk for thousands of traits and diseases. These studies allow users of direct-to-consumer genetic tests to predict their traits and disease susceptibility based on the combined impact of numerous genetic variants. Some of these estimates are available directly from genetic testing companies, such as predictions of height and weight. In this session we will cover how these predictions are formed, discuss current and future medical implications, and review websites which make these predictions widely available to users of direct-to-consumer genetic tests.
