h² heritability, d² inbreeding depression load ratio, \({\sigma }_{a}\) direct additive genetic variance, \({\sigma }_{d}\) inbreeding depression load variance,\({\sigma }_{e}\) residual variance, SD standard deviation, HPD_95%: highest posterior density at 95%
Values correspond to a horse with an inbreeding value of 10%
