Meet Eclyse - the amazing zebra crossing Zorse: Cross between a zebra and a horse. Paint horses don't pick up color in their white areas, hence the zebra.

Meet Eclyse, she is a zebroid (half zebra and half horse)
Log in to post comments By Melissa not verified on 05 Jul permalink A spontaneous crossing - talk about product out-zorse. So perhaps the coloration are tied into that, as discussed above. Calico cats is the classical example of such coloration from x-inactivation. IIRC zebra coloring is dominant which would explain why one seldom sees variants. And I'm not sure about horse colorations, but the local press claimed that white color is dominant.
Which factoids would support an x-inactivation scenario. In a chimera part of the cells have a different set of chromosomes. Either by two separate fertilised eggs who stuck together, or by a rare for mammals 'immaculate conception' and a normally fertilised egg.
In the latter case the normal tissue patches up the parts that don't develop from the cells that have two identical halves of the chromosome set. Have they tested for chimerism? Though the grey hair in between the black stripes is an indication that this is a crossbred.
But there are zebras that are born black and get whiter when they grow up. Log in to post comments By Henk Poley not verified on 05 Jul permalink i am inclined to believe she is real because her patches are brown with blackish stripes, as typical zorses show, instead of white with black stripes.
OK, so she's a whitewashed zorse.

That's my theory and I'm sticking with it! The X-inactivation idea is intriguing, though Log in to post comments By Bob not verified on 06 Jul permalink I didn't believe this was real at first. I never heard of a zorse before.
I really enjoy reading your blog. By the way, you've been tagged. The problem I see with that hypothesis is that it has big patches. Shouldn't the patches be smaller and randomly spread all over the body, like calico cats? I didn't see anything about the size of the patches in my quick scan of the wiki article.
I guess there would be other ways for it to be a chimera, but the likelihood of those other ways happening is WAY too small. Chimeras are very rare as it is. You're sat there, painting a nice new zebra, you just reach over for the grey paint, and the damn thing escapes.
Bob By Bob O'H not verified on 06 Jul permalink Another option is that there was a somatic mutation during early embryo growth, such as loss of coloration. The regions that are white, look very white, albino even.
Different number of chromosomes might make for more instability making such loss more likely. By daedalus2u not verified on 06 Jul permalink actually, the way i understand it is that Ulysses this zorse's sire is a paint horse.
By fireweaver not verified on 09 Jul permalink You certainly see this kind of colouring in cat breeds. I realize they're not different species but the colour-and-white is because of a gene turning off the colour. And I've met lynx-point cats, which are like Siamese in that the cooler areas of the body are darker, but they have pale tabby markings where a Siamese has just colour. I've seen quite a few pictures of zorses and also the efforts to reconstruct the quagga from the southernmost species of zebra.
Eclyse's colours seem familiar, especially the browning of the zebra pattern. The mane also seems hybrid, standing upright for a few inches and then flopping over, like that of an Icelandic horse. Just for fun, this link has an image of an Apaloosa saddle mule!
By Monado not verified on 28 Aug permalink She's a clear case of X-inactivation. She has the x chromosome of both a horse and a Zebra. Because she has two x chromosomes, only one x chromosome in each of her cells is active, "switched on" if you like.
In the stripy patches her mother's chromosome is active, in the white patches her father's chromosome is active. That is also the reason why there are usually onle female tabby cats and rarely if ever male tabby cats. 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. Medium-sized pony mares are preferred to produce riding zonies, but zebras have been crossed with smaller pony breeds such as the Shetlandresulting in so-called "Zetlands".
Donkeys are closely related to zebras and both animals belong to the horse family. These zebra donkey hybrids are very rare. Like mules and hinnyshowever, they are generally genetically unable to breed, due to an odd number of chromosomes disrupting meiosis. Genetics[ edit ] Donkeys and wild equids have different numbers of chromosomes. A donkey has 62 chromosomes; the zebra has between 32 and 46 depending on species. In spite of this difference, viable hybrids are possible, provided the gene combination in the hybrid allows for embryonic development to birth.
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.
The difference in chromosome number is most likely due to horses having two longer chromosomes that contain similar gene content to four zebra chromosomes. Physical characteristics[ edit ] A zorse Zebroids physically resemble their nonzebra parent, but are striped like a zebra. The stripes generally do not cover the whole body, and might be confined to the legs or spread onto parts of the body or neck. The alternative name "golden zebra" relates to the interaction of zebra striping and a horse's bay or chestnut colour to give a zebra-like black-on-bay or black-on-chestnut pattern that superficially resembles the extinct quagga.
Zebra-donkey hybrids usually have a dorsal back stripe and a ventral belly stripe. Zebroid Eclyse Zorses combine the zebra striping overlaid on colored areas of the hybrid's coat.
Zorses are most often bred using solid-color horses. If the horse parent is piebald black and white or skewbald other color and whitethe zorse may inherit the dominant depigmentation genes for white patches. The tobiano the most common white modifier found in the horse directly interacts with the zorse coat to give the white markings.
Only the nondepigmented areas will have zebra striping, resulting in a zorse with white patches and striped patches. This effect is seen in the zebroid named Eclyse a hebra rather than a zorse born in Stukenbrock, Germany, in to a zebra mare called Eclipse and a stallion called Ulysses. Zebroids are preferred over zebra for practical uses, such as riding, because the zebra has a different body shape from a horse or donkeyand consequently it is difficult to find tack to fit a zebra.
However, a zebroid is usually more inclined to be temperamental than a purebred horse and can be difficult to handle. Zebras, being wild animals, and not domesticated like horses and donkeys, pass on their wild animal traits to their offspring.
Similarly, zorses have a strong temperament and can be aggressive. Historical and notable zebroids[ edit ] Zebra-horse hybrid foal with quagga-like markings, Walter Rothschild Zoological MuseumTringEngland InLord Morton mated a quagga stallion to a chestnut Arabian mare.
The result was a female hybrid which resembled both parents. This provoked the interest of Cossar Ewart, Professor of Natural History at Edinburgh — and a keen geneticist. Ewart crossed a zebra stallion with pony mares to investigate the theory of telegonyor paternal impression.
In Origin of SpeciesCharles Darwin mentioned four coloured drawings of hybrids between the ass and zebra.
