  1. Above the diagonal: Pearson’s correlations ± SD between inbreeding depression load genetic values; on the diagonal: percentage of males/females animals in upper (lower) decile of inbreeding load in comparison with the reference population; under the diagonal: percentage of coincident animals in upper (lower) decile of inbreeding load.
  2. IL Inbreeding load genetic value. HofW Height of withers , HatW Height at withers, LofS Length of shoulder, SIL Scapular-ischial length, KK Knock knee, CrN Cresty neck .
