Horses can be cremello (light cream), chestnut (brown), or palomino (gold with white manes and tails). Oddly, breeders have been unable to make a pure-breeding palomino strain. In crosses, breeders see the following results: cremello X palomino: 1/2 cremello, 1/2 palomino palomino X palomino: 1/4 chestnut, 1/4 cremelo, 1/2 palomino chestnut X palomino: 1/2 chestnut, 1/2 palomino How many genes are involved in these results
