a
Registered cattle chosen for minimal pedigree relationships (Heaton et al., 2016). Breed groups were genotyped from whole genome sequence (WGS) mapped to the bovine reference genome assembly (ARS-UCD1.2).
b
The risk allele definitions are listed in Table 2. The sites genotyped from WGS data were chr7:90845941 (BCHF5) and chr3: 84707876 (BCHF2).
c
