Population structure in the Italian vairone. (a) Unrooted neighbor joining population tree based on Cavalli-Sforza & Edwards chord distances (DC) calculated with PHYLIP. The populations from Veneto (pops. 1 and 2), the Po River system (pops. 3 to 19) and Central Liguria (pops. 27 to 29) form a clade that also includes the populations from West Liguria (pops. 23 to 26); the two populations from the Middle Adriatic basins (pops. 20 and 21) form a well supported monophyletic group, just as the populations from East Liguria (pops. 30 to 33) and from Tuscany (pops. 34 to 39). Numbers above the branches correspond to bootstrap values (10000 pseudo-replicates over individuals). (b) Results from the population assignment test with STRUCTURE (K = 5). Again, the individuals from Veneto, the Po River system and Central Liguria are clustered together, their genomes being admixed of two distinct genotype classes. Individuals from the Middle Adriatic basins and from West Liguria fall into two respective clusters; individuals from East Liguria and from Tuscany form a single cluster.
