ABSTRACT

A karyotypic study was performed on the stable swine cell line IB-RS2 cl. 17. A modal number of 37 chromosomes was found and G-banding permitted the characterization of all chromosomes. C bands were located in the pericentromeric regions, while the NORs were visualized in the chromosomes carrying a secondary constriction (G II and G IV-4). The sex chromosomes were also identified.

Keywords: chromosome; ibrs-2; swine; cell; banding methods.
