在人类染色体萤光染色分带法(Q带)和天青-伊红染色分带法(G带和R带)研究的基础上,1971年巴黎人类遗传会议确定了人类染色体分带命名标准,推动了人类染色体分带研究的进展。运用染色体分带方法,解决了一些以往未能解决的问题。Caspersson和其他一些作者应用分带技术,发现慢性粒细胞白血病的Ph~1染色体为第22号染色体的长臂远段易位到第9号染色体长臂远端的结果。其后又发现有的易位到第2号染色体的长臂上。而
Based on the human chromosome fluorometric banding method (Q band) and the azure-eosin banding method (G band and R band), the 1971 Paris Human Genetic Conference established the naming standard for human chromosome banding, Promote the progress of human chromosome zoning research. The use of chromosome zoning method to solve some of the problems can not be solved in the past. Using the banding technique, Caspersson and others found that the Ph ~ 1 chromosome of chronic myeloid leukemia is the result of distal long arm translocation of chromosome 22 to the distal long arm of chromosome 9. Subsequently, some translocations were found on the long arm of chromosome 2. and
