【摘要】 以微铺展法制备豚鼠精母细胞联会复合体标本，经硝酸银染色后作电镜观察，建立了SC组型．与有丝分裂染色体组型比较，发现二者有良好的一致性．在粗线期，X，Y轴的配对区很短，配对区的X轴和Y轴没有明显变细．未发现银染SC具有着丝粒，并对可能的原因作了分析讨论．更多还原

【Abstract】 Synaptonemal comp1exes(SC) in Guinea pig(Cavta porcellus) spermatocytes prcpared with.micro-spreading tcchnique and silver staining were analyzed by electron microscopy. The meiotic SCkaryotype was constructed from 7 cells and compared with the mitotic chromosome karyotype. There is agood agreement between them. At pachytenc, there is only a very shOrt pairing region in which X-andY-axis are not stinct1y thin. The kinctochorc was not found on each SC in our experiments and the proba-ble reason has been discussed.更多还原
