7.染色体桥有图1、图2两种类型。图1中的m、n是某个精原细胞中的一对同源染色体,m为正常染色体,表示相关基因,减数分裂时染色体桥会从两着丝粒间随机断裂,后续分裂进程正常进行;图2中的染色体桥是由一条染色体上的两条姐妹染色单体的末端黏合而成,减数分裂时染色体会在着丝粒间随机断裂,形成异常的染色体,断裂后的子染色体会随机分配到两个子细胞中(箭头表示染色体断裂的位置)。A.图1、图2染色体桥的断裂发生在减数分裂的不同时期B.图2中能正确表示染色体桥状态和断裂位置的图示是乙C.一个精原细胞发生图1、图2变异时,产生异常精子的概率均为1/2D.两种染色体桥断裂后,细胞中的染色体数均等于精原细胞中的染色体数
