Example Embodiment
[0038] According to a preferred embodiment of the present invention, the SNP marker located at the reference sequence Chromosome 1:16,077,935 of the International Porcine Genome Version 10.2 has a T / C polymorphism.
[0039] Wherein, the site is located at the 251 bp of the nucleotide fragment shown in SEQ ID NO. 1, and the difference in bases at this site leads to the difference in the thickness of the pig's back fat and the area of the eye muscle.
[0040] In the present invention, the three genotypes corresponding to the SNP site are TT, TC and CC respectively, the TT genotype is that the bases of the SNP marker site in both alleles are T, and the TC genotype is The bases of the SNP marker site in the two alleles are T and C, and the CC genotype is that the bases of the SNP marker site in both alleles are C.
[0041] Preferably, pigs with the genotype TT at the SNP site at Chromosome 1:16,077,935 in the reference sequence of the International Porcine Genome Version 10.2 ha...

[0113] Example 1
[0114] 1. Experimental animals
[0115] The experimental pig population used in this example is Yorkshire purebred pigs from Hengshui Breeding Pig Farm, Hebei Province, with a total of 384 pigs, including 27 boars and 357 sows.
[0116] 2. Measurement and correction of eye muscle area
[0117] When the body weight of each pig is in the range of 85-105kg, the eye muscle area and body weight of the individual are measured, and the data such as the measurement day and age are recorded. The collected data were corrected for phenotypic data using the genetic evaluation trait determination procedures of the Hebei Provincial Local Standard (DB 13 / T 2065-2014) document "Technical Regulations for Determination of Production Performance in Breeding Farms". At the same time, the pig ear tissue samples of the experimental pig population were collected, placed in PBS buffer, and stored at low temperature.
[0118] When the body weight was measured, the area of the ...
