Northern Dancer
In North America, Northern Dancer is farther back in the pedigree of most major sires, decreasing the risks associated with inbreeding. For example, Tapit, the leading sire in North America 2014–2016, is inbred 3 × 5 to Nijinsky II (thus 4 × 6 to Northern Dancer). He has crossed well with mares from other Northern Dancer lines.
