Figure 3 in Tetraploidy in the Boettger's dwarf clawed frog (Pipidae: Hymenochirus boettgeri) from the Congo indicates non-conspecificity with the captive population
Figure 3. Karyotypes of (A) Hymenochirus boettgeri (IVB-H-CG17-356, male) with 18 homologous chromosome pairs, and (B) Hymenochirus sp. (IVB-H-Hsp06, female) with 10 pairs of A chromosomes and one B chromosome, arranged from Giemsa-stained chromosomes. Chromosomes were cut from metaphase spreads on the left. Long lines in karyotype arrangements indicate the position of chromosome centromere. Short vertical and horizontal lines correspond to the scale = 10 μm.
Figure 4 in Tetraploidy in the Boettger's dwarf clawed frog (Pipidae: Hymenochirus boettgeri) from the Congo indicates non-conspecificity with the captive population
Figure 4. Hymenochirus boettgeri (IVB-H-CG17-356, male), sequential fluorescent chromosome mapping—DAPI, CMA3, C-banding, ribosomal DNA (rDNA) FISH, small nuclear DNA (snDNA) FISH; and non-sequential whole-genome painting on metaphase spread. A, DAPI (black and white, B&W) consistently stains all 36 chromosomes. B, CMA3 banding in green shows nucleolar secondary constriction (NOR locus) on the p arm of chromosome 4 that co-localizes with 28S. C, C-banding (B&W, brighter staining) highlights heterochromatic blocks on telomeric and pericentromeric regions of seven homologous chromosomes (14 arrows). D, FISH with 28S (red) ribosomal probes shows the p arm of chromosome 4. E, FISH with U1 (red) and U2 (green) snDNA probes shows very weak signals. The U1 probe maps to the q arm of chromosome 1, the U2 probe maps to the q arm of chromosome 8. F, genomic in situ hybridization (GISH) with Hymenochirus sp. whole-genome painting DNA probe that hybridizes to all 36 chromosomes with different intensity. Arrows show the less intensely painted chromosome pair. Scale bars represent 10 μm.
Figure 6 in Tetraploidy in the Boettger's dwarf clawed frog (Pipidae: Hymenochirus boettgeri) from the Congo indicates non-conspecificity with the captive population
Figure 6. Schematic representation of the chromosomal location of the U1 (red) and U2 (green) snDNAs, 5S (dark blue) and 28S (yellow) rDNAs, and C-bands (dark grey) in H. boettgeri (Congo) and Hymenochirus sp. (captive population). The haploid A chromosome set of each species, 18 chromosomes in H. boettgeri and 10 chromosomes in Hymenochirus sp., is arranged in descending order of size. The B chromosome of Hymenochirus sp. is depicted separately from the A chromosomes and is entirely covered in grey, as revealed by C-banding. The 5S rDNA locus was not detected in H. boettgeri and is only depicted in the Hymenochirus sp. karyotype. Mapping of the U1 snDNA locus identified a pericentric inversion or copy number reduction/expansion visible on non-homologous regions of chromosome 1. Created with BioRender.com.
Figure 5 in Tetraploidy in the Boettger's dwarf clawed frog (Pipidae: Hymenochirus boettgeri) from the Congo indicates non-conspecificity with the captive population
Figure 5. Hymenochirus sp. (IVB-H-Hsp06, female), sequential fluorescent chromosome mapping (DAPI, CMA3, C-banding, rDNA FISH), non-sequential snDNA FISH, and whole-genome painting on metaphase spread. A, DAPI (B&W) counter-stained metaphase spread shows all 21 chromosomes. B, CMA3 banding in green shows NOR locus on the p arm of chromosome 4. CMA3 signal co-localizes with 28S locus. C, C-banding (B&W, brighter staining) highlights heterochromatic blocks on telomeric and pericentromeric regions of almost all chromosomes. In addition, the whole B chromosome is intensely banded (arrow). D, 5S (green) and 28S (red) rDNA loci are located on the q arm of chromosome 6 and p arm of chromosome 4, respectively. The 5S rDNA is situated on two different chromosomal loci within the single q arm. E, the snDNA loci U1 (red) and U2 (green) are located on the p arm of chromosome 1 and the q arm of chromosome 8, respectively. F, the GISH experiment of the H. boettgeri whole-genome painting probe, which hybridizes on Hymenochirus sp. chromosomes. All chromosomes are painted (red) except one, B chromosome, which shows no GISH signal and is DAPI-positive (arrow). Scale bars represent 10 μm.

Figure 1. Dwarf clawed frogs, Hymenochirus sp. (captive population) and H. boettgeri. A, Hymenochirus sp., female (IVB-H-Hsp06) and male (IVB-H-Hsp02) in amplexus. B, Hymenochirus sp., female in dorsolateral view (IVB-H-Hsp04). In (A) and (B), note the relatively smooth flanks and hindlegs with homogeneous, unenlarged tubercles. C, Hymenochirus boettgeri from the north-western part of the Republic of the Congo (male, IVB-H-CG17-356). D, holotype of H. boettgeri, female (ZMB 11521). The area marked by the red rectangle is detailed in (E). F, Hymenochirus boettgeri from the same locality as the karyotyped individual (IVB-H-CG17-112, male). In (C–F), note the enlarged and spiny tubercles on the flanks and hindlegs typical for H. boettgeri.
