Inbreeding coefficients (diagonal boxes) and genetic relationship coefficients of and among the seven affected stallions calculated from i) pedigree data in bold (upper triangle of the matrix) and from ii) SNP genotyping data in normal font (lower triangle of the matrix).

Stallion code names correspond to the codes in the 5-generation pedigree (Figure S1).
*The diagonal boxes in bold italics with % that should correspond to self-to-self genetic relationship ( = 1) have been used to show inbreeding coefficients for each of the 7 stallions.
