Heritability of FA scores. h2, heritability; HPDI, 95% highest posterior density interval (credible intervals indicating that the heritability of each trait has 95% of probability to lie between the lower and the upper bounds); ΔDIC (p), difference in the DIC between the model with and without pedigree/kinship information (p-value); fixed, significant fixed effects.
