Chromosomal evolution in Mugilidae: karyotype characterization of Liza saliens and comparative localization of major and minor ribosomal genes in the six Mediterranean mullets

Gornung et al offer the first report on the chromosomal locations of 5S ribosomal genes in the fish family Mugilidae. The heterochromatin composition and the major and minor ribosomal gene location suggest that the karyotype of Liza saliens can be considered intermediate between the karyotype of the...

Description
Summary:Gornung et al offer the first report on the chromosomal locations of 5S ribosomal genes in the fish family Mugilidae. The heterochromatin composition and the major and minor ribosomal gene location suggest that the karyotype of Liza saliens can be considered intermediate between the karyotype of the more primitive Mugilidae cephalus and those of the other Liza species and of the representatives of the more derived genera Chelon and Oedalechilus.
