Karyotyping of dog chromosomes is a difficult task owing to the high diploid number of chromosomes (2n = 78) and the similar morphology of autosomes, all of which are acrocentrics. In this report 22 of the 39 G-banded chromosome pairs and their corresponding ideograms have been standardized. The ideogram comprises altogether 235 bands. The need for the introduction of molecular techniques such as chromosome painting and physical mapping of genetic markers for the identification of small acrocentrics is discussed.
由于犬类染色体的二倍体数目很高（2n = 78）且常染色体形态相似，均为近端着丝粒染色体，因此对犬染色体进行核型分析是一项艰巨的任务。在本报告中，39对G带染色体中的22对及其相应的 ideogram已被标准化。该ideogram总共包含235条带。讨论了引入诸如染色体涂染和遗传标记的物理图谱绘制等分子技术以鉴定小近端着丝粒染色体的必要性。
