Co-located 18S/5S rDNA arrays: an ancient and unusual chromosomal trait in Julidini species (Labridae, Perciformes)


	Karyotypes of Thalassoma noronhanum (a), Halichoeres penrosei (b), Halichoeres poeyi (c), Halichoeres radiatus (d), and Halichoeres brasiliensis (e). The chromosomal pairs bearing Ag-NORs are boxed, the silver staining in the upper row. Bar: 5 μm.
