Tests for the presence of outlier loci in cattle breeds, including one test across all breeds (T1), and one test used as a measure of control (T2) where differentiation is expected to be explained by recent genetic drift without any known history of selection

Test	Cattle included	Test type	Performed to evaluate
T1	All	Across all groups (n = 9)	Outliers among all groups
T2	Jutland Kortegaard versus Oregaard‐lineages	Pairwise	Genetic drift in native breed lineages (few/no results expected)
T3	Old bulls pre‐1980 (cryopreserved SDM‐1965) versus Holstein cattle	Pairwise	Native versus commercial breed; selection for local environmental conditions in native cattle
T4	Old bulls pre‐1980 (cryopreserved SDM‐1965) versus Western Norwegian Red‐polled cattle	Pairwise	Two native breeds; selection for different landscape types (rugged terrain in Western Norway, gentle terrain in Denmark)
T5	Western Norwegian Red‐polled cattle versus Western Norwegian Fjord cattle	Pairwise	Two native breeds; selection for polled phenotype (without horns) in Red‐polled cattle
T6	Old bulls post‐1980 (cryopreserved Jutland) versus Holstein cattle	Pairwise	Native versus commercial breed; selection for local environmental conditions in native cattle
T7	Old bulls post‐1980 (cryopreserved Jutland) versus Western Norwegian Red‐polled cattle	Pairwise	Two native breeds; selection for different landscape types (rugged terrain in Western Norway, gentle terrain in Denmark)

A description of cattle breeds and lineages is provided in Table 1.
