This 1997 article by Michael Bowling and R.J. Cadranell mentions the Babolna-bred mare 125 Ghalion (b. 1975), which has only one distant cross to the English Thoroughbred mare 30-Maria, her tail female ancestor (scroll down to the middle of the article for the question about 30-Maria). RJ and Michael calculated that after 125 years and 12 generations of breeding to Arabian stallions, 125 Ghalion was left with 0.024% English Thoroughbred blood. 125 Ghalion is not registered as an Arabian mare. That’s probably because her cross to 30-Maria is in the tail female, which Arabian horse breeders pay particular attention to. (What’s her strain? “Kuhaylan Maria”). Now someone please tell me why Skowronek, with his 9 non-Arabian crosses, would be considered an Arabian horse.
