CYP2C18 gene molecular marker related to chicken carcass skin color traits and application of CYP2C18 gene molecular marker

The invention discloses a CYP2C18 gene molecular marker related to chicken carcass skin color traits and application, and belongs to the technical field of gene detection. The nucleotide sequence of the molecular marker is as shown in SEQ ID NO.1, and Cgt exists at the 430bp position of the nucleotide sequence as shown in SEQ ID NO.1; correlation analysis is carried out according to mutation sites and chicken carcass skin color traits, and it is found that skin yellowness values of breasts, backs, shoulders and legs of TT genotype individuals and overall skin brightness values are significantly higher than those of CC and CT genotype individuals. A pair of specific amplification primers is designed and synthesized according to a mutation site and is used for amplifying the molecular marker, the genotype of the site is determined according to an amplification result, and early selection is performed on the skin color character of the chicken carcass according to the genotype, so that the production cost can be
