Bicolor GISH with the two genomic probes of A (red) and G (green) at mitotic metaphase of interspecific hybrid. Counterstaining was applied with DAPI (blue). (A) Mitotic chromosomes probed with the genomic DNA of O. meyeriana (red). (B) Discrimination of the two different genomes in mitotic metaphase. (C) B with DAPI-stained chromosomes was converted to a black-and-white image to enhance the visualization of the distribution of euchromatin and heterochromatin in chromosomes of metaphase. (D) Mitotic chromosomes probed with genomic DNA from O. meyeriana (red) and 45S rDNA (green). Arrows indicate the position of NORs.
