Abstract

The invention discloses a method for quickly detecting PCR-RFLP (Polymerase Chain Reaction-Restriction Fragment Length Polymorphism) of sequence variation of Chinese native cattle APOA2 gene. The method comprises the following steps: taking the to-be-detected cattle whole-genome DNA (Desoxvribose Nucleic Acid) containing the APOA2 gene as a template and a primer pair P as the primers, and discovering three mutation sites by amplifying the APOA2 gene through PCR, designing three pairs of primers PR1, PR2 and PR2 for the three mutation sites, carrying out digestion of the PCR products by using three restriction endonucleases Bmgt120I, HindIII and HaeIII, respectively, and then identifying the polymorphism of the three mutation sites of the cattle APOA2 gene by virtue of agarose gel electrophoresis. Therefore, a method for DNA level screening and for identifying the polymorphism of a gene closely related to the growth traits of cattle is provided for marker assisted selection (MAS) breeding of the growth traits of the Chinese native cattle, and as a result, a cattle population excellent in genetic resources can be established quickly.

Description

technical field [0001] The invention belongs to the field of animal molecular breeding, and relates to a method for detecting the polymorphisms of yellow cattle APOA2 genes AC_000160.1g.360T>G, AC_000160.1g.424G>C and AC_000160.1g.540A>G, and its growth characteristics in beef cattle The application of marker-assisted selection (MAS) breeding to quickly establish cattle populations with excellent genetic resources. Background technique [0002] In the MAS breeding of cattle growth and development traits, there are two basic methods to study the relationship between DNA markers and target traits: candidate gene analysis and linkage marker analysis. In animal research, candidate gene analysis is easier to operate than linkage marker analysis, and does not require special experimental design, low cost, and strong statistical power. It is widely used and applicable to any population where genotype and phenotype data are available. The method establishes a corresponding...
