The evolutionary development of mammals involves mutations and fixations of chromosomal types. The Y chromosome polymorphism in cattle is important for the breeding strategy, since chromosomal incompatibilities in crossings result in fertility problems. In bulls of various breeds in Switzerland, data on chromosome status have been collected for over 20 years. Data from 7 years were analysed in this study through chromosome measurements and their normalization. Some highly significant differences were found between the 7 groups of breeds, especially between Holsteins and the original Swiss breeds Braunvieh and Simmental. Fleckvieh (purebred or crossbred) did not differ significantly from Black or Red Holsteins. The results were discussed with respect to fertility problems. The observed Y chromosome polymorphism should be taken into account in breeding, and research in this field should be continued.

Fluorescence in situ hybridization (FISH) experiments with specific probes for chromosome 29 and 25 were carried out on a Brown Swiss bull, previously diagnosed as a carrier of 1;29 centric fusion. The hybridization of the chromosome 29-specific probe (BMC 4216 - already located on 29q13), produced signals on two small acrocentrics, but not on the translocated chromosome. The signals appeared on the translocated chromosome and on a single chromosome 25 after hybridization of the chromosome-specific probe (BMC 3224 - previously located on 25q24). According to the actual nomenclature, the analysed aberration is a robertsonian translocation involving chromosomes 1 and 25.
