Big Y AddOn for Google Chrome

FTDNA now provides a button to download BigY results as CSV. The ISOGG tree functionality is also moved to ISOGG Y-Tree AddOn with ability to enter SNPs manually. Hence, making this obsolete.

Enhances FTDNA's Big Y Results with many options! Big Y AddOn is a chrome browser extension that adds additional functionality to Family Tree DNA's Big Y results and plots the results on up-to-date Y-DNA Trees.

The extension adds a number of features to BigY Results
  • Download Big Y SNPs.
  • Download the Known SNPs Table as CSV file which can be opened in Excel.
  • Download the Novel Variants Table as CSV file which can be opened in Excel.
  • Auto-Populates SNPs into MorleyDNA Y-Tree for easy analysis.
  • Highlights Positive and Negative SNPs in ISOGG Y-Tree.

Note: To use this add-on, you must have purchased Big-Y and received the results. Big-Y is a product from Family Tree DNA ( that traces deep ancestry paternal lineage using DNA tests. ISOGG Tree is from International Society of Genetic Genealogy ( Morley Y-DNA Project is a surname project maintained by Chris Morley ( Also note that, markers downloaded and plotted includes only Medium and High confidence and does not include Unknown and no-calls.

Prerequisites: Google Chrome
