Abstract

Dimorphism of satellite chromosomes observed in bone marrow of female as well as male Papio hamadryas, and in continuous cultures of the monkey haemopoetic cells is described. Most frequently the observed dimorphism is expressed in different lengths of satellite arms. The structural dimorphism of satellite chromosomes seen in Macaca, Papio and other genera may seem to originate from different degrees of functional activity of these chromosomes. The active homologue is longer since its satellite arm is less spiralized.

摘要

描述了在雌性和雄性阿拉伯狒狒的骨髓以及猴造血细胞的连续培养物中观察到的随体染色体二态性。最常见的观察到的二态性表现为随体臂长度不同。在猕猴、狒狒和其他属中看到的随体染色体的结构二态性可能似乎源于这些染色体不同程度的功能活性。活跃的同源染色体更长,因为其随体臂螺旋化程度较低。
