Summary of the (co)variance analyses performed in this study

Abbreviation	Methodology	Objective
CT_RRM	Single-trait random regression (CT dataset)	Evaluate the genetic covariance structure of temperament across cows’ lifetime and explore a potential learning and behavioral plasticity component reflected by habituation
YT_CT_MT	Two-trait model (YT vs. CT)	Explore the genetic covariance structure between yearling and cow at weaning temperament (based on a repeatability model)

CT: cow temperament measured at weaning; YT: yearling temperament
