Fig. 5 in Interspecific chromosomal divergences in the genus Characidium (Teleostei: Characiformes: Crenuchidae)
Fig. 5. Karyotypes of the female specimen of Characidium lauroi from Ubatuba, SP, and Characidium lanei from Morretes, PR, after conventional Giemsa staining (a, c) and C-banding (b, d), respectively. Note the different patterns of heterochromatic blocks on the chromosomes and the differentiated sex chromosomes, being the W almost completely heterochromatic in both species. In the box, the Z and W chromosomes carrying the NORs in an inverted position. Scale bar = 10 µm.

Fig. 4. Karyotypes of female specimens of Characidium sp. from Itanhaém, SP, and Characidium schubarti from Jaguariaiva, PR, after conventional Giemsa staining (a, c) and C-banding (b, d), respectively. Note conspicuous heterochromatic blocks in the centromeric region of some chromosome pairs and the differentiated sex chromosomes, being the W almost completely heterochromatic in both species. In the box, the Z and W chromosomes carrying the NORs in an inverted position. Scale bar = 10 µm.

Fig. 2. Karyotypes of female specimens of Characidium cf. zebra and Characidium oiticicai from Salesópolis, SP, after conventional Giemsa staining (a, c) and C-banding (b, d), respectively. Note the differential patterns of heterochromatic blocks on the chromosomes and the differentiated sex chromosomes and heterochromatic B-chromosomes in Characidium oiticicai. In the box, the NOR-bearing chromosomes. Scale bar = 10 µm.
