FISH of rDNA probes on polytene chromosomes of species from the subgenus Chironomus with multiple localization of hybridization sites. a Ch. agilis b Ch. cingulatus c Ch. muratensis d Ch. nudiventris e Ch. pseudothummi fCh. “annularius”g Ch. balatonicus with one NOR h Ch. balatonicus with additional NOR in arm D. Letters designate chromosomal arms. Green arrows show sites of weak hybridizations signals. Bar = 10 µm.
