硬骨鱼类的细胞核移植——鲫鱼细胞核和鲤鱼细胞质配合的杂种鱼

本文用细胞核移植方法,获得了不同属淡水硬骨鱼类之间的核质杂种鱼,即鲫鱼细胞核和鲤鱼细胞质配合的杂种鱼.从观察到的形态特征来看,不论在口须、咽喉齿、侧线鳞片数目、脊椎骨数目等方面,基本上相似于供体细胞核鱼(鲫鱼)的性状.这种杂种鱼已能饲养到性成熟阶段。     

NUCLEAR TRANSPLANTATION IN TELEOSTS——HYBRID FISH FROM THE NUCLEUS OF CRUCIAN AND THE CYTOPLASM OF CARP

Hybrid fish are obtained from the combination of nucleus and cytoplasm from two generaof fresh-water teleosts using the technique of nuelear transplantation (i.e. the combination ofthe nucleus of erueian (Carassius auratus) and the cytoplasm of carp (Cyprinus carpio)). Morphological characteristics of these hybrid fish that have been examined so far indicatethat some features such as barbs, pharyngeal teeth, the number of scales along the lateral line,and the number of vertebrae are similar to those of crucian. Some of the hybrid fish growto normal adult fish.
