摘要: 本文采用表面铺展法, 应用AgNO3及PTA 染色技术研究了达乌尔黄鼠精母细胞联会复合体。根据对10个精母细胞SC 的测量结果, 作出了达乌尔黄鼠SC 的核型, 并与有丝分裂核型进行了比较。本文对XY 配对行为进行了讨论, 同时按性染色体配对特征划分了SC 在粗线期的不同发展阶段。

Abstract:  By means of the surface-spread and stained with AgNO 3 and PTA , the synaptone-
mal complex (SC) of Citellus d auricus′spermatocyte was studied. The SC karotype of
Citellus d auricus was constructed based on the measurement result of 10 spermatocytes
and was compared with its mitotic karotype. The XY-chromosome′s synaptic behavior
was discussed and the different development stage of SC in pachytene was described
based on its sex chromosome′s synaptic character.
