  1. Het: heterozygosity; obs: observed; exp: expected; G: genomic relationship matrix; G diag: diagonal of G refereeing to inbreeding of the animal itself; G off-diag: average of off-diagonal element referring to relationship between animals; A R : allelic richness; pA R : private allelic richness
  2. ***P < 0.0001; *P < 0.01; < 0.05, t-test for differences between obs. and exp. heterozygosities
  3. a, b: no significant difference between A R means for indicated breeds
