在染色体分带技术推广应用以前,理论上曾设想辐照诱致的对称的或不对称的染色体互换畸变的比率是1:1。近几年若干著者为了在辐照后的人体细胞方面证实这个假设,开展了G分带和/或R分带技术工作。迄今为止在人体淋巴细胞只有很少数几篇仍有争论的报导。分带核型图象估价易位频率要比常规染色分裂中
Before the introduction and application of chromosome banding technology, it was theoretically assumed that the radiation-induced symmetrical or asymmetric chromosomal aberration ratio is 1: 1. In recent years several authors have carried out G-banding and / or R-banding in order to confirm this hypothesis in irradiated human cells. So far there are only a few controversial reports on human lymphocytes. Zoning karyotypic images evaluate the frequency of translocation than in conventional staining
