Embodiment 1

[0029] A method for studying genetic homozygosity based on SD rats, comprising the following steps:

[0030] S1. Preparation: Prepare 8 SD rats with healthy limbs, healthy body, 320 g body weight and the same coat color. The SD rats are all 60 days old, with half of the female SD rats and half of the male SD rats, and Half of the 8 SD rats were wild SD rats, and the other half were artificially raised SD rats, and then the 8 SD rats were divided into four groups, the two groups were artificially raised SD rats and wild SD rats, The four groups of SD rats were wild female SD rats and wild male SD rats, artificially raised female SD rats and artificially raised male SD rats, wild female SD rats and artificially raised male SD rats, and wild male SD rats. Rats and artificially raised female SD rats;

[0031] S2, first-generation breeding: place the four groups of SD rats in step S1 in four breeding pens respectively, feed the SD rats in the artificial feeding group every day and...

Abstract

The invention discloses a genetic homogeneity research method based on SD rats. The genetic homogeneity research method comprises steps of performing preparation, performing first-generation breeding,performing first-generation mating, performing first-generation breeding, enabling second generations to be born, performing second-generation mating, and enabling third generations to be born. Fourgroups of the SD rats are respectively wild female SD rats and wild male SD rats, artificial fed female SD rats and artificial fed male SD rats, the wild female SD rats and the artificial fed male SDrats, the wild male SD rats and the artificial fed female SD rats. The invention relates to the technical field of heredity of the SD rats. According to the genetic homogeneity research method based on SD rats, through the wild female SD rats and the artificial fed male SD rats, and the wild male SD rats and the artificial fed female SD rats, the wild SD rats and the artificial fed SD rats can besubjected to comparison mating, so that workers can visually observe the artificial fed situation of the SD rats for the born future generations, and the test accuracy can be improved.

Description

technical field [0001] The invention relates to the technical field of SD rat genetics, in particular to a research method based on SD rat genetic homozygosity. Background technique [0002] SD rats are a strain of rats, belonging to Animal Kingdom, Chordate Phylum, Vertebrate Subphylum, Mammalia, Rodentia, Muridae, Rats, and Rats. SD rats have a long and narrow head and a long tail. Its length is close to its body length, it has more litters, its growth and development are faster than Wistar rats, its temperament is slightly fiercer than Wistar rats, and its adaptability and disease resistance are stronger than Wistar rats, especially its resistance to respiratory diseases. Favored by animal experiments, but its price is more expensive, the current scale of breeding is not as wide as Wistar rats, but it is also a relatively important experimental rat species, and the incidence of spontaneous tumors is low. For research, SD rats need to be mated, and the offspring of SD rat...
