Hinny Hinny A hinny is a domestic equine hybrid that is the offspring of a male horse, a stallion, and a female donkey, a jenny. It is the reciprocal cross to the more common mule, which is the product of a male donkey, a jack, and a female horse, a mare. The hinny is distinctive from the mule both in physiology and temperament as a consequence of genomic imprinting. Hinnies are the reciprocal cross to the more common mule. Comparatively, the average hinny has a smaller stature, shorter ears, stronger legs, and a thicker mane than the average mule. The distinct
Domestication of the horse in the western part of the Eurasian steppe. Both domesticated stallions and mares spread out from this area, and then additional wild mares were added from local herds; wild mares were easier to handle than wild stallions. Most other parts of the world were ruled out as sites for horse domestication, either due to climate unsuitable for an indigenous wild horse population or no evidence of domestication. Genes located on the Y-chromosome are inherited only from sire to its male offspring and these lines show a very reduced degree of genetic variation (aka genetic homogeneity) in modern domestic horses, far
