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.

Giemsa C-banding 방법에 의하여 한국 재래종 옥수수 핵형 및 염색체의 특성을 알아보고자 옥수수의 근단 생장점을 이용하여 조사 분석하였다. 이 방법은 한국 재래종 옥수수의 핵형 분석 및 염색체의 특성 연구에도 효과적으로 활용할 수 있는 방법임이 확인되었다. 조사된 재래종 옥수수에서는 각각 10개의 heterochrornatic knob이 발견되었으며 이것들의 크기와 위치는 계통별로 다른 것으로 나타났고, 모두가 6번 염색체에 부수체를 가지고 있었다. 10번 염색체를 100으로 해서 비교해 본 각 염색체들의 상대적 길이는 조사된 계통별로 큰 차이가 있었다.

A combination of acerocarininc-Wright C-banding technique was utilized to identify each chromosomes in durum wheat ,Triticum durum var. Hordeiforme (2n=4x=28 AABB), This technique elucidated qualitativr and quantitative traits of the indi-vidual chromosomes In coinplement. Most comspicuous bands were observed at thecentromere of B-genome chronmosomes. Each chromosomes of A-genome had some-what weak centromeric, proximal and terminal bands. Chromosomes 2A and 4A hasa small subterminal bands. 6A is smallest and metacentric chromosome and , has two faint interstitial band. Chromosomes 1B and 6B showed satellite and constriction lage band. Short arm of 3B has three heavily interstitial bands. Both arms of chromosome 4B has a lagc centromeric band and a very lage proximal band. 5B had heavilycentromeric band and the long arm showed prominent two interstitial bands. Chromo-somes 25 and 7B has a small terminal band of both arms.
