Notes: a = additive genetic effects, c = shared environmental effects, e = nonshared environmental effect, df = degress of freedom, AIC = Akaike’s Information Criterion, and −2lnL = −2 log likelihood. In parentheses 95% confidence intervals (CIs) are presented below each parameter estimate. A parameter estimate is considered significant if its CI does not overlap with zero.
