Multiple regression models for offspring open-field (OF) behavior. Regression models are created in a step-wise manner. The dependent variable is offspring OF behavior. Model 1 assesses the relationship to the father’s OF behavior. Model 2 adds the possible confounders of maternal care. Model 3 includes all hypothesized confounders and mediators. Male and female offspring are evaluated separately. Significant effects are noted.
