| 摘 要： | 本文以微铺展技术制备中华鳖精母细胞联会复合体标本，经硝酸银染色后电镜观察，分析了SC组型。并与有丝分裂染色体组型相比较，发现二者有着良好的一致性，而且微小染色体的SC结构和着丝粒清晰，未发现形态上有分化的性染色体。中华鳖SC的研究为其细胞遗传学及性别决定机制提供了重要的依据。Abstract Synaptonemal Complexes (SC) in Trionyx sinensis spermatocytes prepared with micro-spreading technique and silver staining was analyzed by electron microscopy. The meiotic SC karyotype was constructed from 10 cells and compared with mitotic chromosome karyotype. There is a good agreement between them. The structure and kinetochores of micro-chromosomes are very distinctive on each SC. There does not exist differential sex chromosome.
