The chromosomes involved in this abnormality were determined using G GTG R RBG and c CBG banding techniques. The chromosomes in question were identified as chromosomes 4 and 10. The existence of 2 paternal half-sisters carrying the abnormality suggests that it originates from the sire. cattle chromosome Robertsonian translocation Resume Une nouvelle translocation chez les bovins Blonde d Aquitaine rob 4 10 . L etude cytogénétique d une population de bovins Blonde d Aquitaine a permis de trouver une nouvelle translocation robertsonienne. Les chromosomes impliqués dans Cette anomalie ont été determines à I aide des techniques de marquage G GTG R RBG et c CBG . Les chromosomes concemés sont le 4 et le 10. L existence de deux vaches porteuses demi-sceurs de père indique une origine vraisemblablement patemelle de I anomalie. bovin chromosome translocation robertsonienne INTRODUCTION Robertsonian translocations are the most commonly reported chromosome anomalies in cattle the most widespread is the 1 29 translocation detected for the first time by Gustavsson and Rockborn 1964 and reported later with high frequency in numerous breeds worldwide Popescu 1977 Popescu and Pech 1991 . The 1 29 translocation is widespread in the Blonde d Aquitaine breed since the .
