Fig. 1From: Asynapsis and unreduced gamete formation in a Trifolium interspecific hybridSomatic chromosomes of hybrid-33. a. DAPI stained metaphase cell; dotted lines show decondensed NORs. b. Same cell as in a after FISH with 5S rDNA (red) and 18S–26S(green) rDNA signals. c. Diagrammatic representation of 5S (red) and 18S–26S (green) rDNA carrying marker chromosomes from T. ambiguum (light grey) and T. occidentale (dark grey) genomesBack to article page
