I'd just like to note, that a lot of bay(or brown, if that's what they really
are) roans have this white frosting on the base of their tails. My gelding has it, and he is not rabicano. Just because a few white hairs are present in the tail, doesn't mean they have to be a rabicano.
I don't mean to sound rude by any means at all, but I see many people that think a bay roan(and sometimes sabinos) with this frosting has the rabicano gene because of it. Maybe the horse IS
really showing a minimal expression of rabicano(and please correct me if I'm wrong), but I see roan horses with this frosting in pictures, in person at public events like rodeos, and in my own horse.
Is this horses [tail] frosting due to rabicano or
Roan? Or maybe even Sabino?
Instant Romance, [reportedly] chestnut roan.
