Pedigree of the three SSCM calves (cases 2–4). The sire of case 2 (IA1) is the paternal grand-grandsire of case 4 and an ancestor of case 3 in generation six. Further ancestors corresponding together in the pedigree of the three cases are marked IA1-IA3. The main contributors to the inbreeding coefficients are IC1-IC5
