Genetic Genealogy is a hot topic in our field. It can tell you an amazing amount of information, but it can also lead you to even more questions. While you do not need to have a degree in genetics to understand your results, or to even use them in your research successfully, I have found those who have a basic understanding tend to do a bit better. This guide is an introduction to genetics for the genealogist and should help answer questions you may not have realized you were thinking about regarding the science behind the tests.
The In-Brief Beginner's Guide to Genetics written by Shannon Combs Bennett contains: Glossary, Explanations of DNA, Genes, and Chromosomes, Inheritance, Tests, Ethics, and many other recommended resources. This 4-page PDF guide can be used on your computer or mobile device.
Shannon Combs-Bennett earned her BS in Biology from Indiana University with the aspiration of becoming a genetic counselor.

She began her genealogy business in 2012 and enjoys researching, writing, and lecturing on a variety of topics including, but not limited to, Virginia, social media, DNA, and lineage societies. Continuing to advance her genealogy education, Shannon completed the Boston University Certificate program in the fall of 2013.
