The Hoechst 33258 - Giemsa banding patterns were compared on axolotl (Ambystoma mexicanum Shaw) and axolotl - tiger salamander (Ambystoma tigrinum Green) species hybrid prophase chromosomes. Approximately 369 bands per haploid chromosome set were seen in the axolotl and about 344 bands in the tiger salamander. In the haploid set of 14 chromosomes, chromosome 3 has a constant short or q-arm terminal constriction at the location of the nucleolar organizer. Chromosomes 14 Z and W carry the sex determinants, the female being the heterogametic sex (ZW). The banding patterns of chromosomes 1, 6, 11, and 14 Z of the two species are apparently indistinguishable by our banding method. In the axolotl, chromosome 9 has a small long or p-arm terminal deletion. In the tiger salamander, the remaining 10 chromosomes have terminal or internal deletions. No translocations or inversions seem to have occurred since the gene pool separation of the two closely related species.
