Why are Falabellas so small?

Falabella horses are small due to a genetic mutation that causes dwarfism. This mutation affects their growth hormone production, leading to a significantly smaller stature than other horse breeds.

Here's a more detailed explanation:

* Genetic basis: The Falabella breed is a result of selective breeding practices over many generations. Breeders intentionally chose the smallest individuals to mate, accumulating the dwarfism gene in their lineage.

* Dwarfism gene: This gene affects the production of growth hormone, a key regulator of body size. The Falabella's genetic makeup results in lower growth hormone levels, leading to stunted growth.

* Distinct phenotype: The dwarfism gene results in a specific phenotype, including:

* Short stature: Falabellas are significantly smaller than other horse breeds, typically standing between 28 and 34 inches tall.

* Proportional body: While smaller, they maintain the typical proportions of a horse, with a slender build and long legs.

* Other characteristics: They are also known for their gentle disposition, intelligence, and strong hooves.

While their small size is due to a genetic mutation, it is crucial to remember that Falabellas are healthy and capable horses, able to engage in a range of activities, including riding, driving, and companionship.
