is the gold standard for predicting genetic merit. BLUP shrinks extreme estimates toward the population mean, accounting for differing numbers of observations and relationships. It is superior to BLUE (Best Linear Unbiased Estimation) when data are unbalanced or when genotypes are related. BLUP is integral to genomic selection (GS), where thousands of markers are used to predict breeding values. Jawahar R
