摘要
采用脾移植实验对额河银鲫 2个不同的雌核发育系进行了遗传分析。在 2个同系移植的组合中 ,移植物被接受的个体数平均 90 % ,表明同一雌核发育系的大多数个体具有一致的基因型。在不同雌核发育系间的移植 ,移植物在 8～ 15天被排斥 ( 2 1℃～ 2℃ )。从而用组织移植证明这些雌核发育系是存在的 ,并对同系移植中出现少数排斥现象的原因进行了讨论。
This paper deals with the genetic analysis by spleen graft test conducted for two different clones of Carassius auratus gibelio (Block).In two groups of isogenetic graft ,the average percentage of individuals with surviving grafts is as high as 90%.This indicates that a majority of individuals of the same gynogenetic clone possesses identical genotype.On the other hand,the grafts between individuals of different gynogenetic clones are rejected within 8 to15 days. The existence of such gynogenetic clones is therefore demonstrated by means of tissue transplantation.The cause for the occasional rejections that occurred in isogenetic grafts is discussed.
