Frances J. Karon, editor of North American Trainer and blogger at Running Rough Shod, brought to my attention Preakness winner Oxbow’s interesting coat color (to the naked eye “roan,” but officially registered as “bay”) as she photographed him during Derby week (see her photo below). As it relates to heritability, his is a curious case. For the Jockey Club to register a grey or roan thoroughbred, one of its parents must also be of the same color. This is not the case with Oxbow. His sire, Awesome Again, is a bay, while his dam, Tizamazing, is a dark bay. However, Oxbow was listed as a “grey or roan” yearling in the Keeneland sales catalog, but his papers reflect the rules of science.
Food for thought: What happens if he starts siring grey foals in the future?
