A zorse generally inherits the striping pattern and some of the conformation of the zebra sire with the size, colouration, and temperament of the domestic mare. Coarse bad tempered pony mares produce coarse bad tempered zonies. Mares of quality, especially Quarter horses and American Paint horses, produce some very beautiful zorses that have a good working attitude. If the mare has a pattern, such as pinto spotting or Appy spots, the zorse often will also. You only see the striping pattern on the pigmented areas, never on the white areas. Breeders avoid using gray mares because the zorse can inherit the graying gene and lose all his stripes in a few years! You can still see the stripes on the skin.
Like mules, zorses are born anatomically normal males or females. They exhibit normal breeding behaviour. But like mules they are sterile. Males should be gelded as early as a few months old to prevent dangerous studdy behaviour. A breeder in KY keeps two zorse mares in the pasture with his Paint stallion to keep him company. He has bred them both hundreds of times over the years but no offspring have ever resulted.
Zorses tend to be very hardy and live into their 30s with good care. Their temperaments are generally similar to those of their mothers, but like the zebra they do have a strong flight response. Because of this it's best for a first time hybrid owner to get a zedonk instead. When a zedonk startles he freezes up like a donkey rather than bolt blindly like a horse or zebra.
