Reynosa Zoo said the zonkey, named Khumba, was born on April 21.
His mother is a zebra called Rayas who lives at the zoo, while h is father is Ignacio, a dwarf albino donkey who lives on a nearby farm.
According to the zoo, Rayas used to visit Ignacio every afternoon and the donkey would also cross into the zoo to see her.
Eventually the zebra got pregnant, surprising the zoo staff.
Khumba is a rare case in the animal world because the zebra and donkey chromosomes are not usually compatible.
