Abstract:
With the objective of characterizing the Q- banding pattern of cattle chromosomes, peripheral blood
lymphocyte metaphase chromosomes of a bull calf (Bos indicus x Bo s taurus L.) were studied using
quinacrine fluorescence banding technique. A karyotype of the Q-banding pattern of bovine chromosomes,
together with a diagrammatic representation and a complete diploid cell is presented. The haploid set of
metaphase chromosomes showed 12S positive bands. A detailed description of the positive bands were
given in the idiogramme, providing accurate description of the banding pattern on individual
chromosomes of this species. This technique is simple and reproducible and can be used in routine
chromosome analysis.
