Ribosomal DNA is active in different B chromosome variants of the grasshopper Eyprepocnemis plorans

B chromosomes are considered to be genetically inert elements. However, some of them are able to show nucleolus organizer region (NOR) activity, as detected by both cytological and molecular means. The grasshopper Eyprepocnemis plorans shows a B chromosome polymorphism characterized by the existence...
