It must have been an old book. People in the US tried to make Palomino horses into a breed but we know now that it's not possible. Palomino coloring is the result of two genes which means crossing Palomino X Palomino will only ever give you a 50% chance of producing another Palomino. Therefore it can't be a distinct breed.
