Abstract

Research workers in veterinary cytogenetics have long been confronted with considerable problems in the identification of individual chromosomes in most domestic animals. Often identification problems have rendered the cytogenetic observations almost meaningless; the analysis has produced very crude and even faulty results. This has particularly concerned the analysis of karyotypes consisting exclusively, or almost exclusively, of chromosomes of similar size and morphology such as the canine, equine, caprine, bovine, and ovine karyotypes. In other domestic animals such as the pig, cat, and rabbit, several individual chromosome pairs have been distinguishable using conventional staining and autoradiographic techniques, but in most cases, even in the latter species, it has only been possible to group the pairs according to size and morphology.
