  • Native American DNA

    How many people in this group have family history that speaks of Native American ancestory but after having DNA Print find that they are of East Asian decent?
    Thanks

    Hi, Joe:

    That has been a very hot topic of discussion on the Genealogy-DNA-L list for some time now. I am one of those individuals who has a solid paper trail and turned out to be 76% Indo European, 24 % EA and 0% AF. However, my group is L1c through mtDNA.

    I am descended from the first Spanish colonists to the island as well as to Criollos and blacks on both paternal and maternal lines. I was born in Puerto Rico and am therefore Amerindian. We have documentation up to 13-15 generations in some lines. Am hoping that the addition of more markers to DNA Print 2.5 will clarify things further.

    For the time being, all we can do is wait until it becomes available.

    Hope we can improve the percentages and shake things up when all the new tests are run.

    Happy Thanksgiving!
    Ana

      Thanks Ana,
      It is good to hear of others. Keep digging.
      Happy Thanksgiving to you and yours!

        Hello,
        I gather that the tests that are being done now are not too accurate from what I have read on these pages. I thought this was going to help me clear things up, now im more confused than ever.
        Ana, is it possible that perhaps since you are mixed, as am I, and this mixture has been going on for many generations, then maybe only what is dominant in your lineage shows up?
        Another tests? More expensive I presume.
        Thank you
        Juan

          It is exactly that, Juan. The DNAPrint tests the other autosomes for specific sequences not the X or Y chromosome. From these autosomes you receive a portion of your ancestry from all your ancestors. It depends how far back that particular ancestor was which determines what you will receive.

          For instance, five generations ago, you had 32 ancestors, but 10 generations ago you had 1024 ancestors. They all contributed to your ancestry.

          You and your siblings should technically receive 50 % of your ancestry from each parent, 25% from each of your 4 grandparents, 12.5 % from your 8 great grandparents, 6.25 % from your 16 great great grandparents, etc. But you and a brother or sister may not receive exactly the same percentage of each ancestry. For instance, if you were looking for Native American and knew it came from both sides, then the % of NA should be greater. If the Native American comes from only one great grandparent or an even older ancestor, it would be diluted by the time you received it and it might not show up at all. There is a +/- 2.5% margin of error in the DNAPrint in determining ancestry up to 6 generations. Also, it is entirely possible that you might receive some, little or none of that ancestry as compared to a sibling. They might show 80% Indo European and 20% NA while you have (like my values) 76% and 24% EA.

          I hope this helps. The DNAPrint seems to be very accurate in determining major ancestry. However, if you have say a small percentage such as 5 % of either NA/EA or SA it may not show up at all on the DNAPrint because there is a 5% margin of error. It may therefore show up as 0%.

          I think I have that right and hope I did not confuse you.

          For a better understanding of the DNAPrint, you might want to read this page:

          Hope this helps!

            Thank you Ana, that kinda clears things up a bit
            I see however that this can work either direction. From what I read you are from Puerto Rico and the population there has been mixing for a long time. In any given family you have a broad range of features from Native American to African, and European. If a people living in an Indian village continually marry outsiders and these newcomers either African or Spanish, then in time the Indian genes would be diluted, although it may show up in some individuals. But suppose the the mixture took place a long time ago as it has in the Caribbean or Brazil and these mixed blood people continue marrying within their same population, within their village, then the original percentages would still be there and shold show up in tests. Also how can people look Indian or African and still test negative for these population groups.
            This is really exciting and although it raises more questions than it answers it (at least for me!) I still think it is a powerful tool.
            Thanks again
            Juan

              Hello Ana, Somehow I unsubscribed to this thread! as you can already tell, im not very computer savy and definately not having an easy time understanding DNA. You have been very helpful and I thank you.

                No problem, Juan. If you have any other questions, I can try and help.

                There is an excellent article concerning admixture in South American groups (I think it was Columbia) which explained the special situation which occurred there. I have to look for the URL for you. and let you know.

                A site you should definitely visit and bookmark is:
                http://www.kacike.org

                This site has many articles re the populations in the Caribe and the haplogroups which are found there.

                BTW, what is your haplotype? and what names are you researching and which location are your ancestors from?

                Ana

                    Oh my Ana, this will keep me up for a quite a few more days! Thank you very much. I dont know what my haplo types are. Pues como comienzo, mi hermano y yo no interesamos en esto hace poco. Nosotros somos cibaenos de la RD. Ya se de los estudios que se han realizados en Puerto Rico y en RD sobre los haplo typos. Pero tambien veo que algunos tienen el haplo typo pero cuando se hacen el BGA test salen negativos........dios mio que raro es todo esto! Im going to surf the net for these sites you gave me right now.
                    Thank you

                      Juan, one of our maternal ancestors was born in Santo Domingo. Believe it or not, another ancestor was Juan de Viloria who was one of the founders of Santo Domingo.

                      Look in the FTDNA surname projects under P and look for the Puerto Rican project. You can come join our project and at least get a lower rate. Who knows, one of your ancestors could have emigrated to PR and you might match with someone in the group. You might have more relatives than you know.

                      Pa'lante siempre!
                      Ana

                        Ana, Thank you for the ftdna.com link! I have been waiting since the extraction dated oct 03 2003 with no reasonable explanation re:the delay.It is now 2004 Now I read there is a transitional process underway, and no telling when the results will be in. I am also mixed Native American [ Illinois] On the genealogy path trying to track this. I do hope its worth the wait. Barbara

                          Percentage?

                          How do you know your Native American percentage? I was tested and it said I was of Haplogroup C.

                            The percentage ancestry test is Ancestry by DNA 2.5. You can learn much more about the test and order it, if you choose, at:

                              Native Americans are FROM East Asia ain't they? That's where they came from before they came to American across the land Bridge over near Alaska,that's what all the scientists say. Native Americans are theoretically one of the tribes of East Asia.
