What is ISOGG?

The International Society of Genetic Genealogy (ISOGG) was founded in 2005 by DNA project administrators who shared a common vision: the promotion and education of genetic genealogy. Our mission is to advocate for and educate about the use of genetics as a tool for genealogical research, and to 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.

Chromosome mapping

Chromosome mapping is a technique used in autosomal DNA testing which allows the testee to determine which segments of DNA came from which ancestor. In order to map DNA segments on specific chromosomes it is necessary to test a number of close family relatives. Ideally one should test both parents, one of their children, and a number of first to third cousins on both the maternal and paternal sides of the family.

Not everyone has close relatives available for testing or has the funds to pay for such testing. Indeed, even if you did test all of more the Genetics Glossary.

How To Search

The easiest way to find pages is to type the subject of interest into the Search Box on the top left 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. Many pages have shortcuts so that, for example, if you type in SNP you will automatically be taken to the page for single-nucleotide polymorphism and NPE will take you to the page for non-paternity event.

Contents Page and Alphabetical List

The Contents Page provides a thematic list of all the pages in the ISOGG Wiki. Additionally the Wiki can be searched from the Alphabetical List of Articles. Alternatively you can browse the pages by searching the Category Tree.
