a

h2r = residual heritability estimate with bolded values significantly different from zero (p < 0.050); σ2C = proportion of phenotypic variance removed by statistically significant covariation (p < 0.100) with sex, age, and sex by age ; h2t = total heritability estimate.

b

Traits for which sex, age, and/or sex by age were significant covariates (p < 0.100) are marked with dots.

c

Traits with low measurement reliability are highlighted in grey.

d

SE could not be estimated for heritabilities equal to 1.00
