Comparative map of the Nile tilapia chromosome LG7. Column 1 corresponds to marker names. All markers are gene-based markers except (a) those with prefix “MS” which correspond to microsatellites (in blue) taken from Lee et al. (2005), (b) those with prefix “WG0” which are BAC end markers (in red) and (c) those with prefix “SNP” which correspond to SNP-based markers (in green). Column 2 corresponds to marker coordinates expressed in centiRays (cR3500). Following columns correspond to comparative data with, from left to right, stickleback, pufferfish, medaka, zebrafish. For every marker, chromosome numbers and coordinates of the putative orthologs in the genome sequences of the four model species are displayed. CSO between Nile tilapia and stickleback/medaka/pufferfish are figured in boxes.
