Results of the analysis of molecular variance (AMOVA) for SNP data indicating the distribution of genetic variation (in %) into the different hierarchical levels.

Dataset Subpopulationa		Total data county	Finland county	Finland region	Sweden county	Sweden region
subpopulation/total	%	0.43	0.42	0.42	0.15	0.03
	p	< 0.0001	ns	< 0.0001	ns	ns
individual/subpopulation	%	1.9	-0.53	-0.37	2.54	2.65
	p	< 0.0001	ns	ns	< 0.0001	< 0.0001
within individuals	%	97.68	100.11	99.96	97.32	97.32
	p	< 0.0001	ns	ns	< 0.0001	< 0.0001

The significance levels for the variance components were based on 20,000 permutations. ns = nonsignificant.

^a denotes the intermediate level of hierarchy used in the analysis
