Correlations between GEBVREG and GEBVAPY of validation animals for broiler chickens. Genomic estimated breeding values (GEBV) are based on the regular inverse (GEBVREG) and the Algorithm of Proven and Young inverse (GEBVAPY) of the genomic relationship matrix. Traits are body weight at grading (BWG), residual feed intake (RFI), breast meat percentage (BMP), and weight gain during feed conversion test (WGT). The number of core animals is defined as the number of eigenvalues that explain 90, 95, 98, and 99% of the original variation
