红白长尾鲫鱼是由彩鲫选育而来的。彩鲫是红鲫、鲫鱼的变种,红白长尾鲫在体色、体型、鳍、鳞被等性状上已与彩鲫有明显的变化,这种变化是否动摇其遗传基础,从而导致生物体遗传物质—染色体数量及核型的变化,本实验想通过核型研究找到两者之间的相互关系,为彩鲫的遗传育种提供理论和技术基础。鲫鱼(Carassius auratus)有:鲫(C.auratus auratus)和
Red-white long-tailed crucian carp is bred from color. The color crucian carp is a variety of red crucian carp and crucian carp. The red - white long - tailed crucian carp has obvious changes with the color crucian carp in body color, body shape, fin, scales and other traits, and whether this change has shaken its genetic basis, Genetic material - the number of chromosomes and karyotype changes, this experiment would like to find the relationship between the two by karyotyping, genetic and breeding crucian carp to provide the theoretical and technical basis. Crucian carp (Carassius auratus) are: crucian carp (C. auratus auratus) and
