Dullahan and Mine That Bird are half-brothers - both out of the mare Mining My Own. They have different sires: Mine That Bird was sired by Birdstone (winner of the 2004 Belmont) and Dullahan was sired by Even The Score. In horse breeding parlance, horses are considered half siblings only if they are out of the same mare. If they only have the same sire, they are just said as being by the same sire. This isn't done because horse breeders no nothing about genetics, but rather to make it easier to keep track of family lineage since a mare can only have one foal a year naturally (not counting twins, which are rare and not desired) verses the 100+ mares a top stallion will breed during the breeding season. And in Thoroughbreds, all breedings have to be 100% natural - no AI, no embryo transfer, etc. The stallion must cover the mare. So because all Thoroughbred breedings must occur naturally, it's impossible for any Thoroughbred to have a half-sibling of the same age (remember the equine definition of a half-sibling). I'll Have Another is out of Archs Gal Edith and is of no immediate relation to Mining My Own. I'll Have Another's sire is Flower Alley who won the 2005 Travers Stakes (nick-named the "Mid-Summer Derby") and was second in the 2005 Breeders Cup Classic. I'll Have Another's pedigree is dripping in staying potential - going strictly by pedigree, he should have no problem getting the 1 1/2 miles of the Belmont Stakes. Mine That Bird and Dullahan are the only ones of the three horses mentioned that are half-brothers. I'll Have Another is not.
