The karyotype of Korean short-hair cat was presented using the G-, C- and NOR- banding techniques. For chromosomes preparation, the fetus skin fibroblast cells were cultured and metaphases were obtained. In results, the Korean short-hair cat had 38 chromosomes with XX or XY, which consisted of 5 pairs of metacentric chromosomes(Group A and C), 3 pairs of submetacentric chromosomes (Group B), 6 pairs of medium metacentric chromosomes except for 1 pair of medium submetacentric D2 chromosomes (Group D, E), 2 pairs of acrocentric chromosomes(Group F) and metacentric X and Y sex chromosomes. In G-banding analysis, the Korean short-hair cat exhibited a typical and identical G-banding pattern in each homologous chromosome. Total number of bands and landmarks on the G-banded chromosomes of Korean short-hair cat well correspond to those of international standardization of karyotype of domestic cat. The heterochromatins of Korean short-hair cat chromosomes distributed at terminal and/or centromere regions on almost chromosomes by C-banding analysis. In addition, the C-banding pattern showed greatly heteromorphic in some chromosomes. Using the AgNOR-staining, we found the nucleolar organizer regions(NORs) of Korean short-hair cat located at chromosomes 1p12 site in E group. The quantity and number of NORs were constant among cells.
