| 摘 要： | 采用界面铺展硝酸银染色技术，研究了公犏牛的精母细胞联合复合体（ｓｙｎａｐｔｏｎｅｍａｌｃｏｍｐｌｅｘ，ＳＣ），结果表明：（１）在减数分裂过程中仅有少数精母的常染色体能形成ＳＣ结构，Ｘ、Ｙ染色体轴 围虽积聚有许多微小的深色颗粒状物质，但未见Ｘ、Ｙ染色体的明显联会（２）在常染色体的联会中，有较多的三价体、插入环等联会异常现象；（３）常染色体ＳＣ相对长度与体细胞染色体的相对长度间有显著相关性（Ｒ＝０９６

| Abstract: | The synaptonemal complex (SC) in spermatocytes of the hybrids (Pian Nui) between yak and cattle were studied by using the surface spreading-silvers staining technique. The results show that, Pian Nui can form the structure of SC in autosomes of a few primary spermatocy-tes and has more synaptonemal abnormalities. There are many tiny sliver pellets around the axes of X and Y chromosomes (like sex vesicle), but there is no obvious pairing between X and Y chromosomes. There is a significant correlation (R=0. 9649) between average relative length of autosomal SC in Pian Nui and those of mitotic chromosomes. Concerning the relative length of SC, there is a significant difference on theSc of No. 1, 2, 27 between Pian Nui and yak, and on the SC of No,1, 2, 27, 29 between Pian Nui and cattle. |
