  1. The following species abbreviations are used (second row): Aj, eel; Ch, Atlantic herring; Dr., zebrafish; Gm, Atlantic cod; Ga, stickleback; Fr, Fugu; Tn, Tetraodon. Using eel as a starting point, the chromosomes/linkage groups/scaffolds with the highest number of connexin genes were identified. The chromosomal location of the corresponding orthologs was identified in the other species (left part of the table). Subsequently, the chromosomal location of the ohnologous genes was identified in the same species (right part of the table). The order of the genes is given by their location on the eel chromosomes. Among the sequences mentioned in this table, there are five obvious examples of tandem gene duplications, indicated by several identical numbers with slashes in-between (e.g., 2/2/2 for cx30.3 ohnolog A in Tn) and one example of a presumed gene duplication located to different chromosomes (cx30.3 ohnolog B in Ch).?, the sequence is unplaced; sc68 and three or four digit numbers indicate scaffold number
