February – All About Segments
This presentation focuses on DNA segments and why they are important in genetic genealogy. Topics covered include displaying segment data, dealing with shared segments and shared ancestors, understanding concepts such as triangulation, imputation, pile-up regions, and chromosome mapping, and working with total shared DNA and Relationship Predictor tools.
March – DNA Painter: Chromosome Mapping
Chromosome mapping is the process of assigning DNA segments to an ancestral line based on sharing the segments with cousins who descend from the line. This presentation explains how to use the Chromosome Mapping feature of DNA Painter to track the DNA you share with matches and to map segments to ancestors.
April – DNA Painter: Trees and Tools
This presentation focuses on the Ancestral Maps and Tools features of DNA Painter. It explains how to create different views of your family tree, with annotations for different DNA inheritance paths, and provides an overview of the Shared cM Project tool and the What are the Odds? tool.
May – GEDMatch

This presentation also reviews the tools available to search the family trees that users have posted on the site.
June – Third-Party Analysis and Visualization Tools
This presentation reviews a number of third-party analysis and visualization tools that are available to assist in autosomal DNA analysis. Topics covered include the Leeds method, several Chrome extensions, the Genetic Affairs AutoCluster tool, the DNAGEDCom Client, and several visualization tools for mapping family relationships.
July – AncestryDNA
This presentation reviews the ethnicity prediction and cousin matching features of AncestryDNA and explains how to use the analysis tools available on the site.
August – Individual consultations
September – TBA
October – Endogamy Explained
Endogamy is the practice of marrying within a limited community or group over many generations for cultural or religious reasons or due to geographic isolation.
