Either because of late glacial or of more
recent migrations the Norway Y chromosome gene pool
appears to be very close to present day Germans. In fact
the Fst and the Fst data indicate Germans and a few other
Central European populations as being the closest to the
Norwegians. When we compare our results with those
based on different polymorphic systems,9,17 we can infer
that these conclusions are also valid for Swedish, while
Finns and Saami had a quite different genetic history with
a great impact of Uralic Finno-Ugric speaking population.
The mtDNA polymorphisms had previously shown the
genetic closeness of Norwegians with Germans, based on the statistic r.8
Our data are consistent with this finding
and support the Y chromosome representation of a strong
genetic influence from central European groups, although
it is less quantifiable.
(Different genetic components in the Norwegian population revealed by the analysis of mtDNA andY chromosome polymorphisms)
According to Cavalli-Sforza, the closest related populations (By genetic distance) are: Germans (13), Dutch (13), Danes (14), Swedes (15), English (16).
NORWEGIAN Y-DNA HAPLOGROUPS
The Norwegian R1a varies between regions. It ranges from 13% in the South, to 19% in the South East near Oslo. It’s maximum is at 31% in Trøndelag.
This type can be split in several undergroups.
R1b is another major haplogroup. This ranges from 26% in Eastern Norway, and the North, to 44% in the West and South. One noticeable thing is that it is a lot more common near the coast than far inland.
I1 is the most common haplogroup on average in Norway, but it varies regionally. It’s lowest percentage is found in the West, 30%. In the North it is 34%. In the South, South East near Oslo, and Trøndelag it is 39-42%.
Halogroup N3 is found at 10% in the North, and a very low percentage in the East and South East. This haplogroup is typical of Finnic-Ugric speakers.
MY SUGGESTION TO HOW THESE HAPLOGROUPS CAME TO NORWAY.
R1b is also most common in Norway, although most common in the West and South, and more found near the coast then inland. I suggest that early settlers brought this type with them. These tribes, who migrated from the Continent abt. 400BC, settled mostly in the West, South and South East. This is the most R1b rich area of Norway. It is likely that these Germanic tribes also brought haplogroup I1 with them. This is the most common haplogroup in Norway. It is noticeable that this type is more common inland than near the coast.The Norway Y chromosome gene pool
appears to be very close to present day Germans (Report by Cavalli-Sforza, 2007).
Tribes of the Goths came to Norway abt. 100AC. They brought the Norse religion (Asatrui). My thesis is that these people brought most of the R1a DNA (Particularly the M17 marker) to Norway.
