Abstract:
PURPOSE: A method for selecting backfat thickness of a pig is provided to measure accurate genetic ability and to raise pig with high quality. CONSTITUTION: A SNP of leptin receptor gene(LEPR) is used as a molecular marker for evaluating phenotype of a pig. The SNPs are -200, -124, -25 or +161 loci mutant based on transcription initiation base(+1). The phenotype is backfat thickness of pig. A microarray for selecting the backfat thickness contains the molecular marker. A method for selecting backfat thickness of pig comprises: a step of obtaining a biological sample having a LEPR gene; a step of amplifying the LEPT gene by PCR; a step of detecting SNP from the PCR product; and a step of selecting SNP having significance in backfat thickness.
