All so interesting.
So I'm wondering....what would happen genetically, if a Gypsy Horse, homozygous for tobiano, were bred to a Zebra? It would obviously be a spotted horse, but would the dark colour, be striped? I'm thinking, maybe so.
Again wondering. In most animals, responsible breeders, breed for good temperament and weed out those who do not have good temperaments. Since hybrids can very seldom reproduce, it would be very difficult to form a line of these striped crosses, with solid temperament in mind. Each would be a new hyrbrid. So I suppose, to get these hydbrids which are more reasonable to handle, the horse used, would have to have an absolutely solid temperament and be known to have already reproduced it reliably. This would likely, produce a more easily handled, Zorse or other Zebra type hybrid.
Certainly, I'm thinking that some breeds of draft horses, with their usually solid temperaments, would be a good cross. I have noticed (I think) that most of these Zorses etc., seem to often take on the body type, of the horse used. So now I'm thinking of how fab a Zorze etc. might be, if half Zebra and half American Saddlebred.
