Genomic information is now useful to identify quantitative trait loci (QTL) which is associated with economic traits as well as to predict genetic potential for individual in Animal Breeding Industry. Especially, genomic BLUP (gBLUP) is one of the useful model to estimate genomic breeding value (gEBV) with genomic relationship matrix (GRM). Genomic relationship matrix will be estimated from genomic information such as single nucleotide polymorphism (SNP) which is similar to numeric relationship matrix estimated from pedigree information used in traditional BLUP. The matrix defines the genetic covariance between individuals based on observed similarity using genomic information, rather than on expected genetic similarity from pedigree. Therefore, gBLUP would be given to better prediction accuracy in livestock breeding.
