This work aims to perform a couple of in silico network analysis from CNVs standpoint, shedding light to possible metabolic connections to tenderness. It was used 671 Nellore males to infer CNVs, through SNP-chip (Illumina Bovine HD Beadchip®, containing approximately 770 thousand SNPs) and PennCNV software methodology. CNV regions (CNVRs) were inferred by CNVRuler (recurrence 0.1).ISAFG 2013. AB.01
