Distribution of the 35S and 5S rDNA loci on the mitotic metaphase chromosomes of the studied Dactylorhiza species. Fluorescence in situ hybridization was performed using 25S rDNA (red fluorescence) and 5S rDNA (green fluorescence) probes to examine the diploid species D. incarnata (paternal lineage) and D. fuchsii (maternal lineage), as well as the allotetraploid D. majalis and autotetraploid D. maculata. Arrows indicate 5S rDNA loci, while arrowheads indicate 35S rDNA loci. Scale bar: 5 µm.
