What is the offspring of a mule and hinny?

While a mule (female horse x male donkey) and a hinny (male horse x female donkey) can both reproduce, their offspring are extremely rare and often sterile.

Here's why:

* Chromosomal Differences: Horses have 64 chromosomes, while donkeys have 62. This difference makes it difficult for their offspring to have a complete set of chromosomes.

* Fertility Issues: Mules and hinnies are typically sterile because of the uneven number of chromosomes. However, there have been rare cases of fertile mules.

* Offspring Viability: The offspring of a mule and a hinny are usually weak and often don't survive long.

Therefore, while theoretically possible, the offspring of a mule and a hinny is a highly unusual and often short-lived event.
