Since its inception Family Tree Dna has been conducting Y-chromosome DNA tests. Originally these were STR tests, then Family Tree DNA began SNP testing. For an explanation of the differences between these tests, see Y-DNA STRs, SNPs, and Haplogroups.
Until today, Family Tree DNA's most recent Y-DNA test was called the Big Y which was a SNP discovery test. But now there is a new, combined Big Y-500 test that is absolutely amazing. Here is how FTDNA describes the new test.
What is Big Y-500?
- The Big Y and Y-111 will be sold together in a product called Big Y-500
- It includes all SNP information currently included in Big Y, as well as the 111 STRs of the Y-111 and newly reported STRs
- Approximately 45 STRs used in the Y-111 product are also reliably called from Big Y data and will serve as additional cross-checks to control the quality of the Big Y-500 product
Where did the 500 come from?
- Approximately 450 STRs were chosen from Big Y data because they can be reliably called on a consistent basis
- Of the ~450 STRs, at least 389 will be reported and when combined with the Y-111, that gives a total of at least 500 STRs
Note: Everyone with Y500 will have 500 STRs (including the Y-111), but not everyone will have exactly the same 389 additional STRs from the Big Y. There will be a significant overlap, but there will be some STRs that are called for one tester that may not be reliably callable for another tester. Big Y-500 STR values will be displayed on the tester's Y-STR results page.

Family Tree DNA has removed the requirement that a man has to order an STR test before ordering the Big Y. Anyone can now order the Big Y-500 and will get a 111- marker STR test, the Big Y SNP discovery test, and hundreds of additional STRs. For DNA Day, the new test is on sale for $649 (regularly $799).

It will be fascinating to see what we can discover about our families with the new Y-DNA data!
