Dr. Clyde, all jokes aside, is there any genetic marker that does not belong to Blacks (African)?

I don't think Genetics really belongs to one particular group from what I understand(I could be wrong) Genetics link us all back to one common ancestor..

^He said R1 originates in Africa, which by implication means Black Africans. This is the typical silly games Afrocentrists play --they use buzz words to get around being overt racialists, yet retaining their racial theories. They can continue to claim heritage and history outside Africa while they argue against race science... smoke and mirrors.

Y-chromosome V88 (R1b1a) has its highest frequency among Chadic speakers, while the carriers of V88 among Niger-Congo speakers (predominately Bantu people) range between 2-66% ( Cruciani et al, 2010; Bernielle-Lee et al, 2009). Haplogroup V88 includes the mutations M18, V35 and V7. The Khoisan (2.2%) carries the R-M269 y-chromosome (Wood et al,2009).
Most Eurasian R1b chromosomes carry the M269 mutation. Cruciani et al (2010) revealed that R-V88 is also carried by Eurasians including the distinctive mutations M18, V35 and V7.
In addition to R-V88 (xR1b1a) we also find R1b. Whereas, R-V88 is associated with Central Africa, R1b is in West Africa and the Sahel among diverse African populations including Niger-Congo speakers such as the Fulbe (Fulani) , Mandekan and Pygmy population (see Figure 2).
Figure 2: Distribution of R1b among African Populations
This figure is based on Cruciani et al (2010).The majority of these African populations speak Niger-Congo languages the Biaka and Twa Pygmies. The Mbuti Pygmies speak a Nilo-Saharan language

^Error up there. There can be no such thing as R-V88(xR1b1a), because V88 mutation defines R1b1a.
The paraphyletic/upstream R-V88 clades are essentially exclusive to Africa. Although R-V88 has fairly low distribution in Eurasia (only 1.1% in Europe and only 0.3% in "western Asia") and generally fall into sub-clades different from the African counterparts, a good case can be made that these are suggestive of gene flow from Africa [Where almost all of the incidences of upstream V88 chromosomes occur] into Eurasia. R-V88* occured only in one "west Asian" individual vs. 95+ % in western-central African distribution.

Why is this an error? Why is Cruciani et al wrong to write: R-V88(xR1b1a) in relation to the V88 mutation?

I already pointed out why it is an error, in plain English. You could not have gotten that from Cruciani et al., because it doesn't make sense. Disagree? Cite the Cruciani et al. passage, in its exact words, that contains R-V88 (xR1b1a)!

Quoted below is total error. They are non-R1b frequencies.
In other words Mandekan, Mossi, Rimaiba, Bamileke, Biaka, Mbuti, and Twa have no R1b MSY-DNA chromosomes in the reported samples.
Fulbe(Burkina) have no R1b
Fulbe(Niger) have 14.3% R1b as R-V88*
Fulbe(Nigeria) have no R1b
Fulbe(Cameroon) have 11.1% R1b as 5.6% R-V88* plus 5.6% R-V69
Ewondo have 3.3% R1b as R-V88*
Above are the correct readings of Table 1 in Crucuani (2010).
Outside of Africa R-V88 showed up in 2 out of 1173 Italians (0.2%), one had subclade R-V35 the other R-V7 1 out of 141 Corsicans (0.7%), he had subclade R-M18 1 out of 510 Balkans (0.2%) and 1 out of 328 Western Asians (0.3%).
5 out of 2152 amounts to 2/10ths of 1%.
Over obviously R-V88 is an African specific marker quite rare to non-existant elsewhere.

Why won't you understand that Y(xR1b)* means every haplogroup except R1b?
This is basic population genetics terminology: Y = the entire set of MSY chromosome haplogroups x = except R1b = R1b including its downstream subclades.
All the other columns in Table 1 are telling you the percise R1b of the subjects.
For example row 1 is of 55 sampled Moroccan Arabs where 1.8% have R1b1b2 but no other R1b haplogroups while the remaing 98.2% have haplogroups that are neither R1b nor any of its subclades at all. There's nothing to debate here.
I know what table the data comes from as seen by the haplogroups and their frequencies provided in my earlier post. Check the figures yourself, you'll see.
BTW Congratulations on your two peer review published articles in Curr Res J Biol Sci.

I read the table wrong. I did not know that x=except. Thanks for making it clear.I would have been embarassed if I had made these statements in an article.
I will admit I am still a novice in this area. But I am still trying to project a different interpretation of the data using archaeogenetics.
Thanks again for the heads up.

I'm dying of laughter here, what a clown. Clyde Winters doesn't know anything about genetics.
Biased clowns like him should stay away from scientific journals.
