“…Several reports on chromosomal anomalies in dogs and canine tumors have been published (Shive et al, 1965;Hare et al. 1967;Ma and Gilmore, 1971;Idowu, 1976, Mayr et al, 1990Bartnitzke et al, 1992a, b;Nolte et al, 1993). In addition, international projects are underway that are aimed at producing a high-quality genetic map for the dog genome (Dog Genome Project, DogMap).…”

In contrast to many other animals, knowledge about the canine karyotype is quite sparse. This is due in part to the rather difficult canine karyotypic pattern. Except for the X and the Y chromosome, there are only acrocentric chromosomes, which appear to be quite small and difficult to identify unambiguously. In previous reports, schematic representations of the canine karyotype have been described. However, a nomenclature comparable to that of the human karyotype or the karyotypes of sheep, cattle, or goats does not yet exist for the dog. Based on high-resolution banding of metaphase chromosomes from canine fibroblasts, we propose an ideogram of the canine karyotype with 460 numbered bands and characteristic landmarks. In addition, the centromere positions of the canine chromosomes are determined by a combined GTG-banding/ FISH approach, and the R- and G-banding patterns are compared.

“…This might account, to some extent, for the remarkable stability seen in the diploid numbers of Felidae and Canidae. Although Robertsonian fusions have been reported in dogs (Ma and G ilmore, 1971;Larsen et al, 1978), the occurrence of such pheno menon in normal individuals is uncommon. were the first to demon strate the presence of NOR on the sex chro mosomes of two species of Seba's fruit bat, Carollia castanea and C. perspicillata, by in situ hybridization of ribosomal RNA.…”

C-banding and silver staining of the somatic and germ cells of the male domestic dog, Canis familiaris, have shown that: (1) the amount of C-banding is small compared to most other mammalian species, (2) three pairs of autosomes have nucleolus organizer regions (NORs) at the terminal ends of their long arms, whereas the Y chromosome has an NOR on the terminal end of the short arm, (3) the organization of the synaptonemal complex (SC) is similar to that of other mammalian species, (4) a distinct SC is formed between the long arm of the Y chromosome and probably the short arm of the X chromosome, and (5) the differential axes of both sex chromosomes do not demonstrate fusiform thickenings nor do they stain darkly with silver as do the XY bivalents in many other mammalian species.

“…The classical form is the reciprocal translocation, which means the exchange of terminal segments between non-homologous chromosomes. At least four diffxent spontaneous translocations (HAGELTORN et al 1973(HAGELTORN et al ,1976LOCNISKAR et al 1976;MADAN et al 1978) have so €ar been described in the domestic pig ( Fig. I C), one single case is known in sheep (GLAHN-LUFT and WASSMUTH 1978) and cattle (MAYR et 21.…”
