1. Trait: TA = Total activity in open field test; TF = Time freezing during cue; FB = Fecal boli after cue; HC = Hematocrit percentage; I75 = Insulin level.

2. Model: (1) = polygenic; (2) = genomic; (3) = polygenic and genomic; with 100/10/2.5% of the markers allowed to have an effect.

3. W: cross-validation within families (all s.e. ≤ 0.01).

4. B: cross-validation between families (all s.e. ≤ 0.03).

5. W: cross-validation within families (all s.e. ≤ 0.02).

6. B: cross-validation between families (all s.e. ≤ 0.04).

7. B: cross-validation between families (all s.e. ≤ 0.02).
