All horses will be at least heterozygous(Aa) for the bay gene, but might also be homozygous (AA). They may have red or black base colors, but all black base color horses will show the bay gene. Possible colors include bay, brown, chestnut, red dun, bay dun, buckskin, palomino etc. Horses might be patterned or solid.
