@Corson Hi, I know my friend very well that when Finland was east part of Swedish Kingdom Swedish was official language and if you wanted succeed good Swedish language was necessary.

If you open this link;

"Dominant Y-chromosome haplogroups in pre-colonial world populations, with possible migrations routes".
You can see that west part of Finland was "blue/Scandinavian color and East part of Finland was green/Finnic color"
Finns arrived to Finland something about 8 000 years ago from somewhere Siberia and Scandinavians arrived from somewhere near current Saudi Arabia.
All the european races have became from somewhere from asia or from middle east.
So, Finland was already genetic mixed (Scandinavia/Finn) many thousands years before Swedish came to Finland in year 1100.
This is what i meant, when i sad that Finland is "mixed race" between Finn/Swedish. When Sweden lost Finland to Russia 1809
all Swedish how lived in Finland stayed to Finland. When Finland become independent 1917 here lived Finns and old Swedish people whose home country was Finland. Today In Finland there's more genetic difference between Western Finns and Eastern Finns than there is between Germans and Brits.

Here are some direct speech from doctoral thesis : "Genetic structure in Finland and Sweden : aspects of population history and gene mapping" ;
"The genetic structure of populations is a potential source of population history information and an important factor in gene mapping studies. The main aim of this thesis was to study the population structure in Finland and Sweden using, for the first time, genome-wide data from thousands of single nucleotide polymorphism (SNP) markers. Furthermore, this thesis introduced a novel gene mapping approach, subpopulation difference scanning (SDS), and tested its theoretical applicability in the Finnish population.

The study subjects included 280 Finnish and 1525 Swedish individuals, and genotypes from Russian, German, British and other populations served as reference data. The results revealed that the Finns differed clearly from central Europeans. Within Finland, the genetic difference between eastern and western Finns was striking. The Finns, particularly eastern Finns, also showed reduced genetic diversity as well as an increased genetic affinity to East Asian reference populations. In Sweden, the overall population structure seemed clinal and lacked strong borders. The population in southern Sweden was relatively homogeneous and genetically close to the Germans and British, while the northern subpopulations differed from the south and also from each other. Overall, these results are congruent with earlier observations from smaller numbers of markers and with population history, particularly the small population sizes that have led to genetic drift. "Although the Finnish gene pool is mainly European, it also harbors distinct eastern elements. Estimates of the relative contributions of these sources to the nuclear gene pool have been 75% European and 25% non-European
(Nevanlinna 1984) or 90% European and 10% Uralic (Guglielmino et al.1990)." Finns appear to be genetically closest to Swedes, Estonians, Germans, and Poles, among others (Seldin et al. 2006, Bauchet et al. 2007, Lao et al. 2008, Novembre et al. 2008, McEvoy et al. 2009, Nelis et al. 2009).

If you are Finn or Swedish or interested about genetic this is fascinating research.
