  • Linkage groups (Co) were randomly assigned numbers, and arm names are given as “a” and “b.” Homologous arms in Chinook salmon, rainbow trout, and Atlantic salmon are based on chromosome names for each species (Ots, Omy, and Ssa, respectively), with known orientations (p is the short arm, q is the long arm).

  • * and ** denote inferred relationship. There were no markers in common between Co07a and Ots11p(*), and there are markers in common between Co12b and Ots34/Ots11p(**).

  • *** A chromosomal arm that is composed entirely of ribosomal DNA.

  • The final column designates chromosomal rearrangements conserved across species; letter corresponds to phylogenetic placement in Figure 5.

  • Incompletely resolved relationships between Atlantic salmon and rainbow trout according to published studies.

  • # might include a section of Ssa19qa.
