植物染色体分带研究虽已有十年以上的历史,由于方法学仍主要停留在带型比较简单的 C 带、N 带,应用方面有其一定的局限性;人类染色体的 G 带成功,特别是近年来高分辨显带的方法学建立,在有丝分裂不同时期的染色体上,已能识别450～850～1700条带,并已进入染色体遗传疾病、癌变机理和基因定位研究的实用阶段。本实验在人类 Although the research on plant chromosome zoning has been more than ten years old, its methodology still lags behind the relatively simple C band and N band, which have some limitations in application. The G band of human chromosome is successful, especially In recent years, the method of high resolution banding has been established. In the chromosomes at different stages of mitosis, 450 ~ 850 ~ 1700 bands have been identified and have entered the practical stage of genetic diseases, carcinogenesis and gene mapping. The experiment in humans
