Genealogical DNA Analysis Tool

Utilizing Autosomal DNA to Research Family Trees


Genealogical DNA Analysis Tool (GDAT) is an app that utilizes autosomal DNA to aid in the research of family trees. The app houses a database of the autosomal data downloaded from various testing companies and provides analysis tools for family history research.

To fully utilize this app, the user should have a basic understanding autosomal research techniques and terminology.

Note that data is stored locally on the user's computer as a standalone database, so access to the GDAT database as well as what data is loaded, rests completely with the user.

If you can not see a full menu on the left hand side of your screen, clicking on the three horizontal lines in the top left hand corner will result in the full menu being displayed.
