what species is a zorse in
Breeding of different branches of the equine family, which does not occur in the wild, generally results in infertile offspring. The combination of sire and dam also affects the offspring phenotype. A zorse is the offspring of a zebra stallion and a horse mare. This cross is also called a zebrula, zebrule, or zebra mule. The rarer reverse pairing is sometimes called a horbra, hebra, zebrinny or zebret. Like most other animal hybrids, the zorse is sterile.
