Question for all you genetics knowledgeable people out there. On gray horses as they fade out, sometimes they will develop "fleabites" where their base color remains in small spots. I have always just heard that referred to as a fleabitten gray. I was recently told that there are different terms that are more descriptive depending on what color the fleabites are; palomino, chesnut, black, etc. Does anyone know if this is true or what the terms may be?
