This episode is based on a technical article examining the fundamental distinction between genotype and phenotype in dairy cattle breeding. It highlights how observable traits and performance are heavily shaped by environmental conditions, limiting their value as indicators of true genetic merit. The discussion outlines how genomic tools enable a more accurate assessment of hidden genetic potential and reduce the risk of selection errors based on appearance alone. At the same time, it underlines that superior genetics require appropriate management conditions to be fully expressed…
