ABCs of DNA | DNA Based Relationship Estimators and Analyzers

The ABCs of DNA is an ongoing series of in-depth presentations on various DNA topics, presented by well-known speakers as well as knowledgeable AGS members.

Topic: DNA Based Relationship Estimators and Analyzers

Presenter: Blaine Bettinger

Description: Explore the tools and methodologies used in genetic genealogy to estimate and analyze relationships between individuals based on DNA data. This lecture will cover how relationship estimators analyze shared DNA segments to predict familial connections. We will discuss the science behind these estimators, including centimorgan (cM) values and segment analysis, and how they are used to build and verify family trees. Attendees will learn to interpret DNA match results, utilize relationship prediction tools effectively, and address common challenges, such as outliers. By integrating these advanced DNA analysis techniques, genealogists can enhance their research, solve complex family mysteries, and validate traditional genealogical findings.
