From: The B chromosomes of the African cichlid fish Haplochromis obliquidens harbour 18S rRNA gene copies
Metaphasic spreads of H. obliquidens after silver staining (a), C-banding (b and c), and in situ hybridization with 5S rDNA (d), 18S rDNA (e), BAC-C4E09 (f), BAC-C5E01 (g), SATA satellite DNA (h) and telomeric (GGGTTA) n DNA (i). (a) and (b) are sequential metaphases. Arrows indicate the B-type chromosomes and arrowheads indicate the chromosome pair 1. Scale bar indicates 5 μm.
