Figure 2.

Graphs of mostly middle-sized chromosomes (unless otherwise indicated) with the default setting of the sliding window size 1 kbp. (a) Medaka shows repeats intermingled with unique sequences resulting in an overall orange coloration alternating with prevailing repeats (green) and unique (red) regions; (b) northern pike, with all acrocentric chromosomes, the largest chromosome shown; (c) betta with repeats localized in interstitial blocks and at a single end of the chromosome resulting in an overall red coloration; (d) sea squirt with homogeneous GC-poor DNA, the smallest chromosome shown; (e) spotted gar, the only fish so far known with the AT/GC heterogeneity, the largest chromosomes shown; (f) zebrafish, an example of an extremely GC-depleted fish genome with almost no fluctuations; (g) Reedfish with extremely large chromosomes without any prominent fluctuations in GC%; (h) fugu, a short linkage group (LG) with an extremely reduced amount of repeats; (i) Salmon, a polyploid AT-rich genome, the largest chromosome shown; (j) Sterlet, another polyploid fish with AT-rich(er) macro- and GC-rich(er) microchromosomes; (k) cat and gorilla (l) are mammalian outgroups with GC- and gene-rich peaks and rather AT-rich repeats.
