origin of the Germanic tribes/DNA analyse

[Hagogoth]

I am very interested in the origin of the Germanic tribes. It is well
known that their most ancient place of origin was the German
Jastof Culture in the Elbe area. But who has lived in Scandinavia?
Other Indo-Euorpean tribes?
Who can give more inforamtion about the DNA-analyse of the Germanic
tribes? I read that partly they are descendants of the south french
Cromagnon, but from Ulrike (Ukraine) and the glacial people from Greece.
When and where did they obtain fair hair and blue eyes? In France?

Well, first of all, Germanic is a ethno-cultural term, not a racial or genetic one, so Germanics are not racially or genetically homogeneous. Racially, perhaps the traditional sub-types for Germanics are the Dalofaelid and the Hallstatt Nordid (and their inter-mixes), but you can find lots of Baltid, Borreby, Keltic-Nordid, Dinarid, Alpinid and Mediterranid Germanics.

Genetically, you'll find also a high level of hetereogenity, if talking about the Y-Chromosome. From majoritarily R1b in England (60%), Denmark (50%), South Germany (50%), Iceland (50%), to more mixed zones such as Germany (R1b: 40%; R1a: 30%) or Norway (R1b:30%; R1a:30%; I: 35%), to majoritary in I such as Sweden (+50%).

Germanics are not a whole mass of people that moved from "x" to "y" colonising enourmous pieces of land. Culture moved more than people, who adopted different cultures. What I mean is that for example the average English Germanic is closer to a Celtic Welsh than to a German, a Flemish Germanic is closer to a Romance Walloon than to an Icelander, etc.

Most of the times culture was brought by a small dominating elite that sometimes represented no more than 2% of the population, and was adopted by the local dominated population.
