The hinny is the offspring of a stallion and a jenny or female donkey, and is thus the reciprocal cross to the more common mule foaled by a jack (male donkey) out of a mare. Like the mule, the hinny displays hybrid vigour (heterosis).[1]: 36
In general terms, in both these hybrids the foreparts and head of the animal are similar to those of the sire, while the hindparts and tail are more similar to those of the dam.[1]: 36 A hinny is generally smaller than a mule, with shorter ears and a lighter head; the tail is tasselled like that of its donkey mother.[1]: 37
The distinct phenotypes of the hinny and the mule are partly attributable to genomic imprinting – an element of epigenetic inheritance.[2] Hinnies and mules differ in temperament despite sharing nuclear genomes; this too is believed to be attributable to the action of imprinted genes.[3]
Fertility, sterility and rarityEdit
According to most reports, hinnies are sterile and are not capable of reproduction.[1]: 37 The male hinny can mate, but the emission is not fertile. Many have no sperm in the emission, others have sperm that is not motile.[4] The dam of a foal carried to term in Henan Province of China in 1981 is variously reported to have been a mule[5] or a hinny.[6]
