Fig. 5.—

Putative conserved and species-specific inversions. (a) The salmonid phylogeny is shown highlighting six different inversion events, each listed according to the Northern Pike chromosome and represented on a dotted line below the phylogeny. Per line (inversion event), white circles indicate the more common or likely ancestral inversion conformation, and black circles the less common and more likely derived inversion conformation. If no circle is present, the inversion was not visible in the linkage map comparison of that species. The putative pericentric inversion across the fusion 9.2–17.1 is displayed in (b) showing two species (Chum and Chinook Salmon) with different inversion conformations, and in (c) for two species with the same conformation (Brook Charr and Chinook Salmon). Predicted centromere positions previously identified in Chinook Salmon (Brieuc et al. 2014) are also shown in (b and c). Full names for species are defined in table 1, the phylogeny is as described in the “Results” section and figure 4, and probable genes within the 9.2–17.1 inversion are shown in supplementary file S4, Supplementary Material online.
