Somatic chromosomes of hybrids 33OP-1 (left column) and 33OP-14 (right column) after DAPI staining (a, d) and FISH (b, e). Diagrammatic representation of rDNA (red 5S; green 18S–26S) marker chromosomes derived from T. ambiguum (light grey) and T. occidentale (dark grey) are shown in c and f. Decondensed NORs, visible after FISH in b and e, are depicted by dotted lines in a and d. Scale bar: 10 μm
