Zetland
Male zebras again can find another mating match for themselves in the form of female shetland ponies to produce hybrids known as zetlands. Given the number of hybrids zebras can create, they surely have a very high fertility match with other species in their family.
There is another term, zebroid, which engulfs all the hybrids produced by crossing zebras with other animals and this includes our zetland. Zetlands have short, squat legs acquired from the pony while the stripes are inherited by the zebra (though they are hard to make out).
