A rare cross between a zebra and a donkey has been born at Reynosa Zoo in northern Mexico.
Zoo officials have named the new arrival, known as a zedonk, Khumba.
Khumba was born on April 23. Khumba’s mother is a female zebra called Rayas while the father is a dwarf, blue-eyed albino donkey named Ignacio.
Ignacio reportedly lives on a nearby farm.
The zoo reported that Rayas used to visit Ignacio every afternoon and Khumba is their love child.
A result from such a mating is rare because a donkey has 62 chromosomes and a zebra has between 32 and 46, depending on the species. Horses have 64. A hybrid has a number of chromosomes somewhere in between. The chromosome difference makes female hybrids poorly fertile and male hybrids generally sterile due to a phenomenon called Haldane’s Rule.
Crosses between donkeys and zebras have been documented since the mid 1800s.
