  1. 1LogL = change in Log likelihood relative to the traditional animal model; P-values are given in parentheses;
  2. σ2AD = direct genetic variance; σ2AS = social genetic variance; σADS = direct-social covariance; σ2C = variance due to common rearing environment; σ2TANK = variance of experimental tank; σ2TVB = variance of the total breeding value; σ2P = phenotypic variance; rAS,AD,T2 = σ2TVB2P; 2bounded to zero; 3the analysis did not converge.
