A high resolution analysis of G-band pattern of normal and aberrant chromosome 1 bearing two linked insertions of homogeneously staining regions (HSRs) in the house mouse (Mus musculus musculus) reveals an inverted pattern of the euchromatic region between the HSRs. On the basis of this analysis, a hypothesis on the causes for appearance of the aberrant chromosome was put forward: the double insertion is a result of inversion of the chromosome 1 of Mus musculus domesticus bearing a single long insertion. The proximal breakpoint is localized inside the HSR and the distal one--between subbands E3 and E4. From the point of view of these data, new symbols for the aberrations are proposed: Ls (HSR, 1C5) 1Icg--for the proximal insertion, Is(HSR, 1D)21cg--for the distal one, In (1) 1Icg--for the inverted region, including the bands D, E1-E3 and the insertion Is(HSR 1D)21cg.
对家鼠（小家鼠）中携带两个同源染色区（HSRs）连锁插入的正常和异常1号染色体的G带模式进行高分辨率分析，结果显示HSRs之间常染色质区域呈现倒转模式。基于此分析，提出了关于异常染色体出现原因的假说：双重插入是小家鼠1号染色体发生倒转并携带单个长插入片段的结果。近端断点位于HSR内部，远端断点位于E3和E4亚带之间。根据这些数据，提出了异常的新符号：Ls（HSR，1C5）1Icg表示近端插入，Is（HSR，1D）21cg表示远端插入，In（1）1Icg表示倒转区域，包括D、E1 - E3带以及插入片段Is（HSR 1D）21cg。
