    What?

    So I assume you are talking about 23andme including the x in the future. Could you please explain "The family inheritance tool has already proven actual GG success". I know once you explain it I will feel silly but...

      I think it will make sense once you get your results.

      There are several people that have discovered family connections using the tool called "family inheritance". It compares Chromosomes 1 through 22 and also the X Chromosome.

      If there are shared haploblocks between you and someone who has shared their data with you, the tool points it out.

      You can join the group of people that are interested in these discoveries. They have set up a Facebook group, it is called Chromosomes in Common.

      One of the members has found 9 other Ashkenazi matches, and several have been able to expand their paper trails.

      I have two such matches, and they are both close geographically as to most distant known ancestors from mine.

      These are not mt or y lines in my scenario, but they certainly could be. Autosomal great-grandparents are still your grandparents, just not mt or y.

      Just be aware, you won't be able to browse a large database to find these people, as it is currently, it is kind of the luck of the draw if you have invited someone to compare, or they have invited you to compare.

      Perhaps, in the future, the company will broaden the scope and allow us all who wish to compare to as many as possible through a new database or something.

        Aahhh!!! Need advice ASAP!!! Me and Mum are ready to buy either DeCodeMe or 23andme, like, NOW, and I am totally confused which to get!!!
        Does DeCodeMe not do the matching service above?

        Does 23andme actually give you your X haploblocks so for example I could use them on that X database people were talking about on another thread?

        DeCodeMe doesn't do haploblocks then, it just shows your X results like a pie chart with no breakdown of X numbers (if that's the right word!)?

        So confused and don't have the money to buy both....I need a test that has the most scope to find out about Mum's father's ancestry (recent and ideally within last 500 years), be it through autosomal, X testing whatever. It would be really nice to find living relatives using the X's if possible.

        Please can someone help?!

          Burto,
          If you do either test you can join this X group:
          http://www.worldfamilies.net/forum/i...p?board=2222.0
          Or the Facebook group Rucksack mentioned.

            Hi Tomcat,
            I didn't think either test gave any useful info on X chromosomes other than a pie chart (in the case of DeCodeMe) which shows the ancestry of both X's combined into one chart? Or have I got that wrong? Does DeCodeMe give any other useful infomaton about X chromosomes or anything I could do further research with?

              Irrespective of differences in analytical offerings, both companies provide users with raw data files showing SNP's sampled and bases found. (There is, I believe, a need to convert nomenclature to a standard format).

              You might visit the X project mentioned. Volunteers there will receive data files (23andMe, DeCode and FTDNA STR's), do needed conversions and integrate data into spreadsheets. They have identified haploblocks on X, are actively researching ancestry correlates to those blocks, and looking into the relationships of SNP to STR results.

              I suppose someone is working with scanners' autosomal SNP's although, I expect, that is proceeding, like X, on a chromosome-by-chromosome basis.

              I think DeCode offers ancestry estimates for X. 23andMe is not doing anything with X, at present, other than disease association, although they have indicated they will 'paint' the X within the year.

              Bottom line: You either take what the companies offer or share your data in the collective interest.

                So I could take lets say DeCodeMe's raw data and submit any of it to any of the current X projects?

                  I do not personally know of any X projects other than the worldfamilies project, but they would accept your DeCode or 23andMe X SNP file.

                    I don't know what DeCode offers as a sharing service and the Facebook group seems to be a 23andMe-based group. But there is no reason why DeCode results could not be integrated (although they may require conversion).

                    Neither scanner defines haploblocks, per se. The Worldfamilies X project has deduced haploblocks by research and comparison of participants' results. (E.G. if a female tester has homozygous X results then the area of homozygosity MUST BE a haploblock and that is borne out by other testers' results that are identical (or nearly so) to the haploblock so defined. Further, the homozygous female tester would SEEM to have had parents of quite similar ancestry and that could be confirmed by the tester's paper genealogy).

                    My understanding is that DeCode simply offers a percentage ancestry estimation for X.

                      23andme results are in...

                      23and me results are in after only 2 weeks.... I am shocked... I was told 10-12 weeks...Right now I am too tired to go through it all... But my autosomal results are 100% European... I found out that the test is testing for heritage past the last 500 years.. I didn't relize that...Of course my Potowomecke heritage is earlier than 500 years ago...It didn't show up untill the late 1650's...Looks like you need to be basically full blooded Native past the last 500 years (something like the in the 1400's) for it to come back Asian....Good luck...Me and another person on this forum recived 100% European, dispite our native heritage. Both 23andme and DeCodeMe show different ways of looking at your ethnic mixture...I am very happy with the results...

                        Congratulations, Maria! You are really lucky. There are many people still waiting for theirs. I hope that means the "Oprah effect" is now over.

                          Hi Maria,
                          Glad you're pleased with your results, but I don't understand the bit about being at least 500 years ago...your ancestor was roughly 350 years ago?
                          And if it's from the 1400's backwards then surely you had even more ancestors that were pure blood in the 1400's?

                            Never meant to show...

                            Hi Burto,

                            Here is what 23andme says about results in reference to European, Asian and African:
                            Before about 500 years, long distance travel was extremely difficult. Most peolpe never traveled more than a few dozen miles from the place of where they were born...As a result, people of European heritage were found exclusivley in Europe, people of African decent were mostly limited to that continent, and so forth...
                            With the advent of European colonialism, however, people began traveling between continents..As a result they often had children thousands of miles from the places of where they themselves were born..
                            Comtempary Aisa, African and Europe-and North America, South America and Australia for that matter-are now home to people of diverse genetic backgrounds.. Thus where your chromosomes sit relative to "Asia," "Africa" and "Europe" in terms of Ancestry Painting is quite likly to be very distant from where you actually live.. Your ancestry painting results should be understood to mean Asia, Africa and Europe before the era of intercontinental travel...about 500 years ago.


                            I didn't relize that it wouldn't show my native heritage (which was about 350 years ago) unless I was born on the North American continent earlier than 500 years ago... The test was never meant to do that..
                            My ancestor, John Waugh, did not come to Virginia till around 1650 or so.. I know that he had 2 sons with my Potowomecke 8th great grandmother, The 2nd son John, born around 1660, is my line. So if you have the $1000, and you want to break your heritage down, it is best to go with DeCodeMe... I will go with DeCodeMe's results.... But I was pleased with the price, the turnaround time and the amount of markers I recieved for that price! I am still glad I took the test...

                              I hope this isn't a case of the questions 23andme asks determines the answers they receive. I think the first half of the statement I have quoted from you above may or may not be literally true, but even if true that more than 50% stayed put, I suspect there was a whole lot of traveling before the advent of colonialism and also before 500 years ago.

                              I know, dropping such a comment may not help and it may be fluff to flesh out the description, too. On the other hand, it may be 23andMe has made analytical decisions based on this assumption. I hope not. I am certain it is a counter productive assumption to weave into its analytical process. My two cents.

                                Native American and 23andme...

                                Is there anyone else here on the forum, besides me (Potowomecke) and David Faux (Mohawk) that has taken 23andme and has native ancestry that came up 100% European on their test...
