“I1b is the most frequent “I” sub-clade in eastern Europe and the Balkans. Its highest incidence was seen in Croatia (31%) and Bosnia (40%). While I1b is seen at low frequencies in western Europe, it is about the only sub-group of “I” seen east of the Adriatic. I1b is virtually absent among Italians, Germans, French, and Swiss. This may mean that I1b also expanded out from a LGM refugium - but this one located in eastern Europe or the Balkans. The highest diversity of I1b STRs was seen among Bosnians, Croats, Czechs, and Slovaks, and the lowest diversity was seen among the Turks and Moldavians.
The sub-clade I1b2 (M26) is usually seen at very low frequency in western Europe, but occurs at higher frequencies in several isolated spots: Sardinia (41%), Castile (19%), Bearnais (8%) and Basques (6%). The differing distributions of I1b2 and I1b indicate that those two groups probably separated before the LGM. The authors feel that the high concentration of I1b2 in Sardinia may not necessarily mean that the haplogroup originated there. The unusually high Sardinian frequency could also be explained by I1b2 being present among the first humans who colonized that island about 9000 years ago, which was subsequently amplified by genetic drift. The study did not test for P41b, or M161, the mutations that define, respectively,
I1b1 and I1b2a.”
