In an interspecific human-Chinese hamster hybrid that retains 13 and 85.6% of the chromosomes of each parental complement, activity of nucleolus-organizing regions (NOR) of both type chromosomes is observed in 18.9% of the cells. Interspecific chromosomal associations are also noted. Unlike the parental lines of Chinese hamster cells, the hybrids show the associations of the NOR of Chinese hamster chromosomes. In hybrid cells, there occurs partial suppression of NOR activity in human and Chinese hamster chromosomes, while the NOR of the 3d chromosome of the Chinese hamster is completely suppressed.
在一个保留了每个亲本基因组13%和85.6%染色体的种间人-中国仓鼠杂交细胞系中，在18.9%的细胞中观察到两种类型染色体的核仁组织区（NOR）活性。还注意到种间染色体联会。与中国仓鼠细胞的亲本系不同，杂交细胞系显示出中国仓鼠染色体NOR的联会。在杂交细胞中，人类和中国仓鼠染色体的NOR活性出现部分抑制，而中国仓鼠第3号染色体的NOR则被完全抑制。
