This report

indicates that what it calls R1b1b2* is the most frequent variety of R1b1b2 in every region of France studied, except Alsace, where U152 was the most frequent subclade.

The SNP L21, which is apparently very common in France, was not part of the testing. That raises the question: How much of the "R1b1b2*" in that study is actually L21+? Most of it? Half of it?

I have written the corresponding author of the study, but thus far have received no reply. Perhaps if someone here who speaks and writes Spanish would write, that might help.

It seems L21 was discovered just a bit too late (October 2008) to have been included in this study, which tested for all the other major R1b1b2 subclades.

Look at the regions that were tested in that study (http://download.journals.elsevierhealth.com/pdfs/journals/1875-1768/PIIS1875176809002340.pdf):

"Nord-Pas-de-Calais (Lille), Bretagne (Rennes), Alsace (Strasbourg), Île-de-France (Paris), Auvergne (Clermont-Ferrand), Provence-Alpes-Cote d’Azur (Marseille) and Midi-Pyrenees (Toulouse)."

In all of them except Strasbourg, R1b1b2* (untested for either P312 or L21) was the most frequent variety of R1b1b2.

That is pretty startling.

Like I said in the previous post, all of the major R1b1b2 SNPs were tested for except P312 and L21.

Maybe it shouldn't be, but for R1b1b2* (untested for P312 or L21) to be the number one haplogroup in EVERY region tested, except Strasbourg? Doesn't that seem at least somewhat surprising to you?
