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.

Objectives

  • 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.…

Upcoming Events

Genealogy Lock-In

May 19, 3-8pm, Digital Media Room (2nd Floor), Iowa City Public Library

3:00-4:00pm Iowa Genealogical Society instructor Linda Greethurst will present "My Tree is Sick... What Can I DO?" She'll explain how you can save lots of time and frustration by analyzing your sources and facts so you can avoid a painful and major pruning of your family tree later. Greethurt herself discoved that a long researched branch of her own family tree was not only sick but based on fiction at best. 

4:00-5:00pm Iowa Genealogical Society President Kevin Spire will discuss using Google in genealogical research. 

5-5:45pm Dinner Break

5:45-8:00pm ICPL After Hours: If you want to stay for the after-hours part of our day, please join ICPL staff in the Digital Media Lab on the 2nd floor by 5:45pm as the Library will be closing at 6:00pm. You'll need to be in the Lab before the library closes. (You can leave at any time). You'll have access to the library’s print and online resources to either begin your tree or find a new piece of information, and ICPL staff and members of the UI Personal Genome Learning Center will be here to help where we can. From experienced researcher to new to genealogy, all are welcome!

May meeting of the DNA Interest Group - Iowa City

How Genes Inform Drug Therapy

May 22, 6-7pm, Meeting Room A, Iowa City Public Library

A discussion of how genetic variations can be used to predict an individual’s response to certain pharmacological drugs. The presentation will focus on explaining the link between genetics and drug metabolism, analyzing DTC and clinical pharmacogenomic testing resources, and discussing cases in which pharmacogenomic testing can have an impact on drug therapy.
