Introducing Y-DNA for autosomal DNA testers

This presentation was originally given as part of Genetic Genealogy Ireland 2020. \n \nMany DNA testers have started with autosomal DNA testing.  For these people Y-DNA is still a mystery. This talk is aimed at those already using genetic genealogy but are curious about Y-DNA testing.  I will explain the Y-DNA test and results in basic terms to help those starting out.
