Relationship between length and coverage of reads for sequences harboring the FISNA domain. Coverage has been normalized for each species by dividing the coverage for each sequence with the average for that species. The average lengths of genes with the FISNA domain is 17 kbp in cod and 14 kbp in haddock, and the increased coverage in sequences about this length might indicate that there are multiple, very similar regions with these genes in the two species. The cod sequences larger than 10 Mbp represent the linkage groups. Cod is plotted with red and haddock in blue. The x-axis is log(10)-transformed since the sequences span from 700 bp to more than 20 Mbp
