[Metbod] Cell division was synchronized by the pepripheral blood lymphocyte culture and the excessive dosage of thymine deoxyribonucleoside, and R-band of Cervus nippon hortulorum chromosomes was also analyzed by RBG-banding technique. Result The number of haploid chromosome banding increased to 400. The R-band of No. 1, No. 2, No. 3, No. 4, chromosome X and Y were almost just opposite to the high-resolution G band of them. The terminal of chromosomes except No. 21, No. 24 and No. 28 were all pos- itive deeply stained. E Conclusion] R-band of Cervus nippon hortulorum chromosomes can be manifested by RBG-binding technique.展开更多
