Hinny
offspring between a male horse and a female donkey

The hinny is a domestic equine hybrid, being 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 distinct from the mule both in physiology and temperament as a consequence of genomic imprinting; it is also less common.
Many supposed examples of the jumart, which were thought to be a hybrid between a horse and a cow in European folklore, were found to be hinnies.
Description
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).
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. 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.
The distinct phenotypes of the hinny and the mule are partly attributable to genomic imprinting – an element of epigenetic inheritance. Hinnies and mules differ in temperament despite sharing nuclear genomes; this too is believed to be attributable to the action of imprinted genes.
This brief starts where responsible research should: with the source description of “Hinny” as offspring between a male horse and a female donkey. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as offspring between a male horse and a female donkey. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 19, 2026. The linked authority identifier is Q217584. The Library of Congress control number is sh2004001503. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
