Resumen:
The Argentine Creole is a local breed of cattle with high reproductive perfomance. This breed also shows resistance to many subtropical diseases. The cytogenetic status of the Argentine Creole, in particular the incidence of 1/29 translocation and Y-chromosome morphology, is not known in Argentina. Taking these factors into account, the cytogenetic study of 36 Argentinian Creole bulls was carried out. Heparinized blood samples were obtained and cultured for chromosome analysis. The results showed the absence of the 1/29 translocation in all the bulls analyzed and the presence of a submetacentric Y chromosome.
