| 摘 要： | 本文研究了白化高原鼠兔的毛色遗传及白化现象的生化成因。结果表明,高原鼠兔的白化性状是受隐性基因控制的稳定遗传性状,白化成因在于白化鼠兔体内不能产生足量的黑色素。文中还对白化鼠兔的有关特征和野生色鼠兔进行了比较。

| Abstract: | An albino group of plateau pika (Ochotona curzoniae) was bred in the laboratory of our institute. The hair-color heredity and biochemical cause of albino phenomenon of plateau pika were studied. The results mainly are as follow:
( 1) The albino characteristics of the pika, white hair and red eyes, are controlled by recessive genes and can be inherited steadily.
( 2 ) The characteristics of wild-color pika, brown hair and black eyes, are controlled by dominant genes.
( 3 ) The cause of albino phenomenon of plateau pika is due to the albino pika can not produce enough quantity of melanin.
( 4 ) Genes which control albino characteristic of plateau pika are not distributed on the sexual chromosomes.
In this paper, the growth and development of albino pika are compared with those of wild-color plateau pika. There are no obvious differences in them, but litter size of albino pika is less than wild-color pika. |
