Matrix of genetic differentiation (pairwise FST) for 14 a posteriori-defined wild boar subpopulations in Europe. Colour gradient represents the degree of genetic differentiation: low for FST<0.05, moderate for 0.05<FST<0.15, high for 0.15<FST<0.25 and very high for FST>0.25, according to the criterion for genetic differentiation by Wright (1978).
