Yarovit,
Props for trying to introduce genetics here. DNA can be a very useful investigative tool when it comes to history. However, you seem to have made a bit of a mess of the facts. If I may...

I would like to share with a very interesting map that I found on one of Polish history forums. It depicts the percentages of Y-chromosome haplotypes among European indigenous (non-immigrant) male population. It is clearly visible how mixed Europeans are and that racial and national classifications are artificial.
Yes, native Europeans are mixed, but they're usually mixed with other Europeans. Haplogroups such as R1, I, J, etc. are of West Eurasian origin. West Eurasian is a new term for Caucasian, White, etc.
Also, there are many problems when using Y-DNA haplogroups to sort so called "races". It can be done to a point, but only in the right context, because here we're talking about ONE gene carried by males only. And as we all know, humans carry many genes that make us what we are, and females also contribute.
Thousands of genetic markers carried by both males and females are needed to sort humans into "races", or rather, more correctly, continental genetic clusters.

The haplogoups (or haplotypes) are fundamental mutations that endured inside the Y-chromosome. They are useful in determining what ethnic groups contributed to modern European genetic stock.
Not really. Many gross generalizations have been made in recent years about these Y-DNA haplogroups, even by qualified scientists. These should be ignored.

Here are some conclusions that we came to:
R1 haplotype is identified with pre-Indo-European indigenous population. It split relatively recently onto two subgroups - northeastern R1a and northwestern R1b.
J haplotype is identified with indigenous pre-Indo-European population of Southern Europe and Middle East.
N haplotype is identified with Ugro-finnic stock.
I haplotype is identified with Indo-Europeans (Kurgan cultures) who at one point invaded Europe from the Pontic steppe where they originated and assimilated culturally its population.
ExE3b is most likely a Turkic/Central Asian haplotype.
E3b is thought to have originated in North Africa.
Actually, R1a is the haplogroup tied to the Kurgan culture. But that might not be correct anyway, so it desn't matter.
Latest data tells us the following...
R1a, R1b and I1 have been in Europe since the Paleolithic, and were carried by very robust looking proto-West Eurasians (Early Modern Humans, in scientifc terms). J, E, G and F came to Europe later during the Neolithic. These people were also West Eurasians, but later "models" from the Near East, and introduced agriculture to southern Europe.
So basically, modern native Europeans are largely of Paleolithic European origin, with some Neolithic Near Eastern admixture, mainly in the south.
There is also some Uralic admixture in the north, linked to haplogroup N dispersals. But due to heavy mixing for thousands of years, many of the people carrying N in Europe now look very Scandinavian, like in Finland and Sweden. That's because they carry haplogroup N, but the rest of their genes are of European not Uralic origin.

Honestly, I thought that Poles would be much more diversed due to position just in the middle of Europe and the fact that Poland is a flat country, which makes it perfect for invasions.
A good example of how historical facts can be corrected with science. But obviously this has to be done very carefully...
Poles are actually one of the most homogenous nations in Europe. The initial ethnogenesis of the nation, which saw the largely Paleolithic derived (R1 and I) locals form into Slavs and then Poles, has not changed much in over 3000 years.
New lineages were introduced over that time, like N from the Baltics, but their impact has been minimal. Most of the admixture has been rather insignificant, or very similar to the original Poles anyway. In fact, there has been a whole report written on this topic, titled "Homogeneity and distinctiveness of Polish paternal lineages revealed by Y chromosome microsatellite haplotype analysis".

Nationalists and racists will point out how different human populations are, even at nation state level. At the same time, anti-Nationalists will try and show how mixed they are. In the end, none of this helps in our understanding of human genetics, biological diversity and history.
But luckily, DNA tests are now becoming very detailed and thus their results less prone to wild misrepresentations. The picture we're getting is that humans can be divided into different groups, depending on the markers used, and some of these groups do approximate our old notion of "races". However, we have to also understand that all humans are extremely closely related. In fact, many large regions, like Europe, are practically inbred when compared to other animal populations.
