What union specifically results in the creation of a zonkey?

Answer

A male zebra and a female donkey

A zonkey is explicitly defined as a hybrid resulting from the specific mating combination of a male zebra serving as the sire and a female donkey serving as the dam. This pairing determines the genetic input that creates the hybrid's distinct characteristics, such as the zebra's striping pattern overlaid onto the donkey's physical structure.
