What is ISOGG?
The International Society of Genetic Genealogy (ISOGG) was founded in 2005 by DNA project administrators who shared a common vision: promotion of and education about genetic genealogy. Our mission is to advocate for and educate about the use of genetics as a tool for genealogical research, and promote a supportive network for genetic genealogists.
This Wiki was established for the benefit and education of the genetic genealogy community. To contribute to this Wiki please join ISOGG (it's free!). If you don't have information to contribute enjoy reading the articles on this website.

Tips for Searching the Wiki
The easiest way to find pages is to type the subject of interest into the Search Box on the top-right of your screen. As you type, a drop-down list of pages will appear. Click on a suggested page to view it or click the very bottom of the list where it says "containing" to view every mention of the search term in the ISOGG Wiki. Abbreviations can also be used as navigation shortcuts so that, for example, if you type in SNP you will automatically be redirected to the page for single-nucleotide polymorphism, NPE will take you to the page for non-paternity event and atDNA will take you to the page for autosomal DNA.
The Contents Page provides a thematic list of all the pages in the ISOGG Wiki. Additionally the Wiki can be searched from the Index, an alphabetical listing of all articles in the Wiki. Alternatively you can browse the pages by searching the Category Tree.
