双着丝粒染色体，病理名，染色体异常类型之一。
目的探讨用多色荧光原位杂交(M FISH)技术检测的易位和双着丝粒染色体畸变的差异。
Objective To explore the differences between radiation-induced translocation and dicentric chromosome aberrations detected by multicolor fluorescence in situ hybridization (M-FISH) method.
对于1号和4号染色体，辐射诱发的易位率、双着丝粒体率的观察值与基于DNA含量的预期值相比，差异皆无显著性。
For radiation induced translocation and dicentrics in chromosomes 1 and 4, no significant differences were found between the observed frequencies and expected frequencies based on DNA content.
