“A Systematic Approach to Validating Ancestry DNA Thrulines: The Good, The Bad, and the Ugly” – By Diana Elder
Presentation:
We’ll explore how ThruLines helps you identify potential relatives through shared DNA segments and visualize genetic connections. However, not all Thrulines may be correct. Learn about the limitations so you can set realistic expectations. Discover strategies for overcoming common pitfalls in ThruLines, such as faulty family trees and false positive matches. We’ll examine the DNA research process, including assessing matches, analyzing pedigrees, and setting clear research goals. You’ll learn to evaluate ThruLines hypotheses by analyzing DNA evidence, verifying historical records, and identifying false positives to ensure the accuracy of your research.
