Find Missing Men on Your Family Tree | YDNA for Genealogy Course | YDNA Class

YDNA testing can reveal deep geographic origins and genetic connections dating back much further than the 5 generations revealed by autosomal DNA. This YDNA masterclass teaches you the skills to understand what your YDNA is telling you–and to use YDNA testing effectively to answer specific questions about paternal lines.

Here’s what people are saying about the YDNA Course

My dad’s paternal grandfather was illegitimate and I have no clue who his father was. A clue came up [in the Course] which may break down [this] long-standing brick wall. This is fantastic! I now have something to work with to try to discover my GGGfather. Thank you!


The Course was great: love the pacing, the style, the humour, and the down-to-earth advice. My biggest win was digging into the family project info and actually making use of those big tables of data–and finding connections between matches I hadn’t made sense of before!


I had searched high and low for good YDNA information and was always disappointed. This class surpassed my expectations by so much! My biggest win is my new understanding of haplogroups and haplotrees. It is wonderful now to be able to follow upstream and downstream on my haplotree….If you want to get the most out of the YDNA test, you need to take this class.


My biggest win was finally understanding my father’s YDNA research and how to interpret the DNA project data. If you’re struggling with understanding YDNA, interpreting your match results, or just want to learn more about how YDNA can help you in your research, this is the course for you!


What do I get with this course? What is the format?

For the 3 weeks of interactive instructive, plan to spend 2-3 hours per week on in-depth, self-paced, online instruction and practice. (Some people may work more quickly than others, and some may want to dive deeper. That part is up to you.) You’ll experience:

  • About 6 total hours of pre-recorded video tutorials (average 2 hours per week)

  • Classwork and homework that provide hands-on experience with real-life case studies

  • Quizzes, polls, and a discussion board moderated by experts

  • Live wrap-up Q&A session via Zoom at the end

  • Enrollment in a class cohort that allows students to interact with one another at their preferred level

  • Full-length, printable professionally-created workbook with classwork, homework, and research log (PDF format) becomes a useful reference guide for you later

  • Digital download edition of the handy YDNA Quick Reference Guide by Diahan Southard

Do I need to have access to a YDNA test to take this Course?

It’s best (but not required) that you already have access to a YDNA sample at Family Tree DNA.* (The cost and ordering of DNA testing itself is not included in the course.) These can be your own (if you are a genetic male) or someone else’s (if you’re a genetic female and/or you’re exploring a paternal line other than your own). If you’re using someone else’s test results, be sure you have their permission and the login access.

However, while there are times in class when you will be looking at and working with your own DNA results, this is a hands-on learning experience from which you can learn all you need to know without even having your own YDNA results. We will provide several case studies from which homework assignments will be given that do not require your own YDNA test results. And because you will have access to the Course permanently, you’ll be able to come back and review what you need to.

Are there any prerequisites for the YDNA Workshop?

We don’t recommend this course if you’re brand new to DNA testing. We’d like to see you if you’ve got at least a little bit of experience working with or learning about DNA matches. Taking the DNA Skills Workshop first is not required, but we recommend you take it at some point as part of your overall DNA research training.

Preferably, you will have a research goal or question in mind when you take the course, but it’s not required. Sometimes you’ll discover a research question or goal as you begin learning.

What technical requirements are necessary? Is there a textbook?

This course takes place online. During these weeks, you’ll need a reliable internet connection for streaming the video learning sessions and for additional learning on your own time. You’ll need access to your DNA test results on whatever testing site you’re using. You’ll receive a unique PDF YDNA workbook and additional reference materials that support your learning.
