The size of a mule or hinny is influenced by the size of both parents. Since you're asking about a miniature donkey stud, the resulting mule would likely be smaller than a regular mule.
Here's a breakdown:
* Miniature Donkey: They are much smaller than standard donkeys, typically standing around 30-34 inches tall.
* Horse: Horses can come in a variety of sizes, from miniature horses to draft breeds.
Therefore, the size of the mule would be somewhere between the miniature donkey and the horse mother. It's impossible to give a specific size without knowing the size of the mare involved.
Other factors influencing mule size:
* Genetics: Just like with any offspring, genetics play a role. Some mules might inherit more of their mother's size, while others might be more similar to their father.
* Nutrition and environment: A mule's diet and living conditions can also impact its growth.
Important Note: Mules are sterile, meaning they cannot reproduce. This is because donkeys have 62 chromosomes and horses have 64, resulting in an uneven number (63) in mules.
