Results of the hierarchical analysis of molecular variance (AMOVA) for the CL and TW lines of A. fraterculus

Source of variation	Degree of freedom	% Total variation	Fixation indices	P
CL line
Among generations	2	3.16	FCT = 0.03158	0.066
Among replicates Within generations	3	2.64	FSC = 0.02724	< 0.001
Within replicates	310	94.20	FST = 0.05795	< 0.001
TW line
Among generations	2	1.15	FCT = 0.0115	0.056
Among replicates Within generations	3	2.65	FSC = 0.0268	< 0.001
Within replicates	314	96.20	FST = 0.1148	< 0.001

The degree of freedom, the percentage of variation, the F statistics and the probability (P) estimated from the permutation test are given at each hierarchical level.
