The Glossary is divided into three major groupings based on the origin of the term: Genealogy, Genetics, and the Industry. The full table of contents below maintains this group but provides a quick link to all the terms. Look on each each group heading for a definition of that grouping itself. Realize that this glossary is in the context of genetic genealogy and a surname study and often does not follow strict definitions used in biology or genetics in general. The terms Family Branch, Genetic Genealogy, and Surname Study are not defined here as they have top level pages in this wiki.
