The G-bands at late prophase, prometaphase and metaphase chromosomes have been induced, and the number of G-bands of a cultivar decreases gradually from late prophase to metaphase.
Objective To explore the methods of karyotyping and G-banding of Schistosoma japonicum chromosomes and analyse the characteristics of the karyotype and G-banding pattern.
目的探索日本血吸虫染色体的制作及其G带显带方法，进一步分析其染色体核型和G带带型特征。
