 its not that noticable on a grey compared to a picture of a chestnut(maybe 
 bay) that I saw.I don't know if its dominant or recessive or "other".Her 
 sire,maternal grandsire,another horse by her sire and his son none have 
 it.Mybe someone else can explain the genetics of it. >>

It is apparently nutritional--if there is a genetic component, it is simply a 
matter of being oversensitive to a deficiency of whichever micronutrient has 
been implicated.  I'm having a "senior moment" about it and can't remember 
what micronutrient it is--but I do know this comes up from time to time on 
the various Arab boards, and invariably someone remembers the right answer...
