  1. 1 L, long arm; S, short arm; D, distal (interstitial) location of 5S rDNA; P, pericentric location of 5S or 35S rDNA; ST, subterminal location of 35S rDNA; chr, number of the chromosome.
  2. 2Scale bar = 1 μm; only the chromosomes bearing rDNA are shown: filled and open circles indicate position of 35S and 5S rDNA loci, respectively.
  3. 3Heterozygote; both chromosomes carrying 35S rDNA (chromosome 3 and chromosome 6) are shown.
