Fig. 7From: Karyotype differentiation in 19 species of river loach fishes (Nemacheilidae, Teleostei): extensive variability associated with rDNA and heterochromatin distribution and its phylogenetic and ecological interpretationMitotic metaphases of selected nemacheilid species after TSA FISH with telomeric (TTAGGG)n probe. a N. binotatus, b S. corica, c S. notostigma (karyomorph with 44 chromosomes). Chromosomes with the telomeric repeat probe (green colour) are counterstained with DAPI, pseudocoloured in red colour for better contrast. Arrows point to the chromosomes with ITSs (a). Arrowheads show telomeric probe covering entire p-arm of st chromosomes (c). Bar = 10 μmBack to article page
