Fig. 4.

Chromosomal segments showing the conserved syntenic blocks containing Sox2 in several fish species, including the cichlid O. niloticus. Vertical color bars indicate the same gene in the different species (left) and its respective genomic position in relation to several other genes (right). The most conserved genes among fish and other vertebrates are underlined. The interrupted vertical lines indicate the genomic positions of the genes in reference to the scaffold 243 of O. niloticus genome that was used as reference. See Supplementary Material S4 for more information on the gene abbreviations.
