  1. 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, HPD95%: highest posterior density at 95%
  2. Values correspond to a horse with an inbreeding value of 10%
