    The way I understand FTDNA's Free SNP Test Offer is, when you order a Haplogroup confirmation test that does not come back positive, they will do additional test, gratis, until they find the correct Haplogroup. I'm not sure how they would/could test for for a Haplogroup that is not in their database.
    Yes, I believe you are correct that they will do additional free testing to determine the correct haplogroup if they had predicted it wrong. However, I was talking about situations where the haplogroup can not be reasonably predicted.

    Keep in mind the difference between haploTYPE and haploGROUP. Your haploTYPE is your series of STR results (ie, your markers). For every 12-marker Y-DNA test, FTDNA predicts your haploGROUP based on your 12-marker haploTYPE. How? In most cases, there are already people in the FTDNA database and in Dr. Hammer's database with the same 12-marker haploTYPE as you. One or more of those people had their haploGROUP confirmed by SNP test. So FTDNA can use this information to predict the haploGROUP for future testees who have the same haploTYPE. They don't do SNP tests for every person to determine their haploGROUP.

    However, there may be times when someone comes along with a rare 12-marker haploTYPE that is not already in the FTDNA database. I recall reading on the boards that if FTDNA can't reasonably predict the haploGROUP for this person based on haploTYPEs already in the databases, they will do a free SNP test to determine the person's haploGROUP. Providing the haploGROUP is part of their service, so they won't just guess at it or leave it blank. Doing the SNP test in this case is a necessary part of providing the results back to the customer. And, it helps to contribute to FTDNA's database so that when someone else comes along with this rare haploTYPE, they'll now have the information to predict the second person's haploGROUP.

    It's possible that I'm remembering this wrong -- I'll see if I can find the post(s) that mentioned this. In the meantime, here's a page on FTDNA's website that discusses some of this:

      Thanks, Elise.

      That was helpful to me.

        Tucson, Arizona - Family Tree DNA President Bennett Greenspan announced today that what looks like alien DNA has been discovered in Laboratory Batch #147, which was received at the genetic genealogical testing company's facility at the University of Arizona in Tucson on April 5.

        "We have evidence that extra-terrestrials are living among us," Greenspan said.

        The company is withholding release of the test results until the NSA, CIA, NASA, and the President have been fully apprised of FTDNA's findings.

        Sources within the Pentagon have confirmed a rumor that a detachment of elite Delta Force commandos has been dispatched to Prince Edward Island in Canada in connection with Greenspan's news.


        [The above news story is entirely fictional.]

        It's true..i was called an Alien at the US border once!...

        how do you guys know an Alien when you see one?

          It's all in the license plates.

          Every time I have driven into Canada I've been asked, "Got any guns in your vehicle?"

          When I say, "No," they just smile and say, "Enjoy your stay with us," and wave me on through!

          Guess I don't look like a gun nut (I'm not), and having a little kid in the car probably doesn't hurt.

          They've never searched my vehicle.

            Yes, you are right: I read right through "TYPE" since you were talking about SNP testing. Great response.

            • Okay, I'm back from Burger King.

              Let the fun begin!

              Where are my results?

              • Good night once again, folks!

                Well, since nobody is talking and I don't have my results yet, I guess I will go to bed.

                Another day of waiting down.

                Four more to go, counting tomorrow.

                C'mon 147!

                  Stevo - You cannot go to bed yet! Tonight may be the first time results will come in on a sunday night.

                  • Put a Q-tip swab under your pillow tonight.
                    maybe the DNA Fairy will visit you.

                    • Genographic Results Received!!!



                      I just received the Y-DNA results of one of the cousins of my very rare Virginian surname and it was a 12-marker match! We always believed that his great, great grandfather and my great, great grandfather were brothers, but they were both out of the household of our great, great, great grandfather long before 1850 (the first year of REAL census-taking).

                      Anyway, his Genographic Project kit was mailed in just a few days apart from my other same-surname cousin whose Batch 147 sample went to FTDNA. Batch 147 results are probably just around the coroner...oops...I ment corner!

                      ...hehehe..."just around the coroner"...ancestry humor!

                      • I continue to suspect that the influx of Genographic kits is exactly why all of our FTDNA results have been delayed.

                        • Good morning, all!

                          Will today be the day?

                          Maybe.

                          Anyway, my target date is Friday, May 19, and that's drawing closer.

                          Still, I guess there's no guarantee I will get my results by then.

                          My personal page does warn that the target results date is a ballpark lab estimate.

                          Oh, well, they'll come when they come.

                          And I'll be the same guy.

                          I'll just have more questions, probably.

                          • good morning Teach.

                            This is supposed to be the week. I must say I'm excited about this snp test.

                            It's a sunny day here...about 20c...Perfect weather for results.

                            • any second now

                              I assume all you folks have spent as much time looking at results time for other batches and calculating, but using all my middle school science teaching skills...I'd say any second now we should get our results.
                              Seriously, Tuesday or Wednesday seem to be popular days for results.

                              • Off topic, RootsMagic

                                I hope I don't offend anyone on this thread by getting off topic, but...
                                If you haven't settled on genealogy software, take a look at RootsMagic. It feels simple to me like paf, but it did some very nice error checking on my GEDCOM. I haven't really done much with the report writing part of it yet.
                                Have a good day, and remember -- results are just around the coroner.
