[It's not a question about ethnicity but of social class.]
You can't separate the two in the statistical sense, in terms of distributions. Those are like the sock and the boot. Even finns and fennoswedes in Finland have it combined. If the relationship were to break down, it would mean that separate ethnicities would not exist any more and a new combined ethnicity has emerged.
