¹LogL = change in Log likelihood relative to the traditional animal model; P-values are given in parentheses; σ²_AD = direct genetic variance; σ²_AS = social genetic variance; σ_ADS = direct-social covariance; σ²_C = variance due to common rearing environment; σ²_TANK = variance of experimental tank; σ²_TVB = variance of the total breeding value; σ²_P = phenotypic variance; r_AS,AD,T² = σ²_TVB/σ²_P; ²bounded to zero.
