  • Brazilian-African celebrities DNA

    In another forum, I found a link to an article about DNA tests of some Brazilian-African celebrities (unknown to me, of course):
    http://www.bbc.co.uk/portuguese/noti...sileiras.shtml

    It's in Portuguese - so I didn't understand all. One should click on the various people to read about their genetic makeup. Mostly, they seem to discuss some autosomal test (which they take as very precise... oh well...)
    But they also did a basic Y SNP and mtdna test. Unfortunately they seldom say the actual haplogroup, as far as I understand. Of the few I could grasp, Frei David dos Santos is Q3 (!) and some Native American mtdna haplogroup (so A-D, presumably). Sandra de Sa is some african mtdna, and her father is "a rare African Y hap present among the zulu and in western africa"? (rare and Zulu - one would almost say A, but then western africa?). Ildi Silva is L3, and her father I1a. Of the others, not much is said, other than they are european or african haplogroups.

    If anybody speaks portuguese and finds more info in there, it could be interesting.

      African diaspora



      ABSTRACT We analyzed sequence variation in the

      mitochondrial DNA (mtDNA) hypervariable segment I

      (HVS-I) from 201 Black individuals from two Brazilian

      cities (Rio de Janeiro and Porto Alegre), and compared

      these data with published information from 21 African

      populations. A subset of 187 males of the sample was

      also characterized for 30 Y-chromosome biallelic polymorphisms,

      and the data were compared with those

      from 48 African populations. The mtDNA data indicated

      that respectively 69% and 82% of the matrilineages

      found in Rio de Janeiro and Porto Alegre originated

      from West-Central/Southeast Africa. These estimates are

      in close agreement with historical records which indicated

      that most of the Brazilian slaves who arrived in

      Rio de Janeiro were from West-Central Africa. In contrast

      to mtDNA, Y-chromosome haplogroup analysis did

      not allow discrimination between places of origin in

      West or West-Central Africa. Thus, when comparing

      these two major African regions, there seems to be

      higher genetic structure with mtDNA than with Y-chromosome

      data. Am J Phys Anthropol 133:854–867,

      There’s a nice list of African haplotypes in Brazil.

        It's kinda hard to believe ain't it?

        Oprah probably is a Zulu,but America's not one to discuss or make a big deal over people's ethnicities. Kunte Kinte an authentic person brought over to work as a slave as told in Alex Haley's book "Roots",was from the Mandingo African tribe of Gambia,Senegal,and Ginnea Bissou-they still live there today. I've read of other American Blacks who tested and were from the Ibo tribe and the Mende tribe. I'm sure Oprah is a real Zulu,just as I'm sure I'm a real ,well....whatever-I'm not sure if my group is mostly Germanic or mostly Hispanic??

          Nice write-up and translation, Bracari - and it's nice to see Dna testing's being done the world over.

            I guess I have a story to tell . . . Back in the old days when Oprah co-hosted “People are Talking" my mother's university group attended every once in a while. So, every once in a while, it becomes a big event to see Oprah on the television; it is like that when you have seen someone in person. So, of course, when the PBS genetic documentary aired, it was nice to hear about all of the genealogies. Alex Haley's book and television show were awesome events to live through. Now we are able to live the adventure ourselves with the help of genetics. Still, for people whose families have been in America for some time, I do not think many people could claim Zulu? I remember from Star Trek, Uhura spoke Swahili which would be more like an Afro-American. Still, I did not know the Zulu people spoke Bantu.

              GregKiroKH2:

              I think you are right about the Zulus. The scientific papers I have seen show that very few slaves came from the Zulus. Most Africans brought to the US are from Western Africa, some from West-Central (Congo and Angola) and some from Mozambique. But South Africa and Eastern Africa didn't contribute much. This fits well with the historical picture.

                I just discovered this topic on the DNA testing of Afro-Brazilians.

                Obina is in haplogroup J on his Y-DNA side. That's awesome! Does anyone know if he is J1 or J2?

                  Unfortunately the article didn't mention if Obina is J1 or J2 !

                  All the Best !

                    Checking the article linked above, I think I understand that it says that the haplogroup is common in the middle east and among jews and arabs. Then it says that it is about 6.5% in Portugal, and various proportions in other European countries.

                    A paper by Beleza on Portugal finds J2 to be about 6.5%, while J1 is more like 3%. So if the journalist is correct, this points to J2, despite the reference to Jews and Arabs. But of course we should always be a little skeptical of journalists' reports. In any case, J2 is more frequent in S Europe than J1.

                      That would be awesome if he is a J2 I think that there is a good chance that he is. The percentages that you list above make sense.

                        I just looked at the Brazil project as well. There is more J2 in it than I would have predicted
