Mule?

Ears say it is NOT a horse, tail says that it either a horse or a hinny, so what is it?

It looks like a mule, but the tail says that is is a hinny. But with hybrids are you always be sure?

For example: everyone knows that mules have large ears, like a donkey.
Hinnies have ears longer than a horses, but shorter than a donkey's.

But I saw a photo of a half Arabian horse hinny. It had very short little ears.
Arabian horses have a gene for ears that are smaller than other horse ears, and this was dominant over donkey ears.
