New SNP for I1-Z73+

Today came the results of kit 121192 Nissilä/Suomela WTY. Have found two SNPs - L1301, L1302. Let me remind you that the branch Suomela "Z73 +", which departs from the "Z58 +". Its area of ​​distribution is mainly Scandinavia.



Besides Z73 + found in the offspring Varangian Šimon. (Šimon would live in Kievan Rus' for the rest of his life, and he first served Yaroslav I the Wise and later his son.) Quite possibly the new SNPs will help us in the future to understand the migration of the Varangians.

German mtDNA in Russia.

In the article "Russian ethnic history inferred from mitochondrial DNA diversity Irina Morozova et al." we find very interesting facts:

Being quite distant from the Finno-Ugric group, the Southern Russians consequently differ from the Northern Russians in their closeness to the Germanic group. This difference indicates that the Germanic people played a significant role in the development of the southern, but not the northern segment of the Russian gene pool. In general, the Germanic influence on the formation of the Russians is not as obvious as the impact of the Slavic, Baltic, and Finno-Ugric people. However, strong interactions between the Germanic and Slavic tribes have been found in archeological materials dating from the mid-first millennium B.C. to the early first millennium A.D. These interactions were the strongest on the northern coast of the Black Sea, in the area of the multiethnic Chernyakhov archeological culture (second to fifth centuries A.D.). In the second half of the first millennium A.D., the descendants of this culture colonized the southern regions of the historical Russian area (Sedov, 1994, 1995). However, there is no evidence in the historical literature of the interaction between the Germanic tribes and the Slavs (and later, the Russians) after the Slavic colonization of the East European Plain. Therefore, the Germanic influence could not have occurred after the early part of the first millennium A.D., which was before the eastward Slavic migration (Sedov, 1994, 1995). Apparently, the impact of the Germanic people on the Chernyakhov Slavs affected the gene pool of modern Southern Russians, consequently differentiating them from the Northern Russians (Fig. 6).  
 It is worth noting that the Ryazan region, though attributed to the central Russian group has a distinct attraction to the southern group, is clearly seen in Fig.5


Apparently this is another confirmation of the words of the historian Jordanes that the Gothic king took Ermanaric Oka river basin: “thiudos: Inaunxis Vasinabroncas Merens Mordens Imniscaris Rogas Tadzans Athaul Nauego Bubegenas Coldas”.
 

Primary areas of subclades Z58+, Z63+ and L22+

I think at this stage of the primary areas of good loom for Z58+, Z63+ and L22+. Britain did not consider, as in the UK are well represented all of the subclades. Perhaps this is a consequence of various migrations in Britain - Vikings, Angles, Saxons, Normans, etc.

New publication. New SNP?

There was a new publication - Contemporary paternal genetic landscape of Polish and German populations: from early medieval Slavic expansion to post-World War II resettlements // European Journal of Human Genetics

 Geographic locations of studied populations on an ethnolinguistic map of Central Europe in the early 20th century (Slavic and German-speaking areas are marked in green and red, respectively). 1 – Kaszuby; 2 – Kociewie; 3 – Kurpie; 4 – southern Polish pre-war population, studied by Woźniak et al.; 5 – Lusatia; 6 – western Slovakia (Bratislava region); 7 – Mecklenburg; 8 – western Bavaria (Augsburg region).

Statistics on haplogroup I1.









"A total of 39 different haplogroups have been detected in the studied sample set, including an insertion polymorphism at M91 (M91insT wish a stretch of 10 thymidines) previously observed in two individuals from a large woridwide sample set."

And probably for I1 found new SNP. I speak about SNP M91. Probably in this place there was insertion since M91 marks haplogroup B-T. About it probably also tells "M91insT" inscription.

I think to representatives of all branches of I1 (Z58+, Z63+, L22+, M227+, DF29+, Z131+, M253+) it is necessary to check this SNP. While it is possible to tell that the branch doesn't have this new SNP Z382+.
