Karyotype and Fluorescence in situ Hybridization in Plectorhinchus mediterraneus. Karyotype of P. mediterraneus composed of 24 acrocentric chromosome pairs (A). Double-FISH treatment to localize simultaneously the 5S rDNA (red) and 18S rRNA genes (green) (B); U2-U5 snRNA gene (red) and 18S rRNA gene (green) (C); and U2-U5 snRNA gene (red) and 5S rDNA (green) (D).
