DNA MARKERS USING LEPTIN RECEPTOR GENE AND USES THEREOF

摘要

DNA markers by using leptin receptor gene are provided to determine economic traits of pigs including back fat, fat content and lean percentage, improve selection efficiency of seed pigs and genetic ability of seed pigs selected, and manage meat quality of pigs. Molecular markers for estimating economic traits of animals employ genes associated with obesity including a promoter region of leptin receptor gene, wherein the molecular marker is single nucleotide polymorphism(SNPs) that is at least one mutation on a locus selected from -792, -303, -201, -687, -707 or -763 from a initiation starting base. A method for selecting a seed animal comprises the steps of: (1) determining SNPs on a certain locus of an obesity-related gene such as a promoter region of leptin receptor gene; and (2) analyzing the economic traits of animals based on the determination results. Further, the obesity-related gene is a promoter region of the leptin receptor gene.
