However, when a mule (63 chromosomes) tries to reproduce, the cells contain . The 31 donkey chromosomes cannot align perfectly with the 32 horse chromosomes. They form "univalents" (chromosomes without a partner). Consequently, the mule’s body cannot produce viable sperm or eggs.

Because horses are generally larger, breeders must take care to ensure neither animal is injured during the process. Today, many breeders use Artificial Insemination (AI) to ensure safety and higher success rates. 5. The Role of the Mule Today

[Horse Parent: 64 Chromosomes] --> Contributes 32 \ --> [Offspring: 63 Chromosomes] / [Donkey Parent: 62 Chromosomes] --> Contributes 31

When a horse and a donkey mate, the resulting hybrid is either a mule (male donkey and female horse) or a hinny (male horse and female donkey), both of which are usually sterile due to having 63 chromosomes [23, 24, 25, 27, 28]. While mules are more common and known for hybrid vigor, both types display a mix of physical traits and distinct vocalizations [25, 26].

Humans breed horses and donkeys specifically to create a hybrid animal that possesses the best traits of both parents:

A hinny is the offspring of a male horse (a stallion) and a female donkey (a jenny). Hinnies are much rarer than mules. This scarcity is largely due to domestic supply and reproductive mechanics; jennies are typically smaller than horse mares, making the pregnancy more physically taxing, and stallions are often less responsive to jennies than jacks are to mares. Visually, hinnies tend to look more horse-like, often possessing smaller ears and a mane and tail more similar to a horse, though they usually remain closer in size to their donkey mothers. Reproductive Behavior and Breeding Challenges

often inherit the body shape and smooth coat of a horse but have the long ears, small sturdy hooves, and thick heads characteristic of a donkey. However, when a mule (63 chromosomes) tries to

Because of the 63rd chromosome, the reproductive organs (gonads) develop, but the process of meiosis (cell division to create sperm or eggs) fails. The chromosomes cannot pair up correctly to divide. However, it is a myth that they have no sex drive. Male mules are gelded (neutered) to prevent aggressive behavior, while female mules (molly mules) can have working ovaries but almost never conceive.

Horses and donkeys belong to the same taxonomic family, Equidae, and the same genus, Equus . However, they are entirely distinct species with different chromosomal counts.

The primary barrier to full compatibility lies in their chromosome counts: 64 chromosomes (32 pairs) Donkeys: 62 chromosomes (31 pairs)
