What genetic trait results in the short, sturdy legs of the Pembroke Welsh Corgi?
Answer
Achondroplasia
The most visually striking physical attribute of the Corgi—its short legs—is specifically attributed to a genetic condition known as achondroplasia, which is essentially dwarfism. This trait is essential to their historical function, as the low-slung engineering provided a low center of gravity, allowing them to effectively herd stubborn cattle by avoiding kicks, as they could easily duck under the swing of a hoof. Despite their shortness, the legs are required to be straight, strong, and possess a heavy bone structure appropriate for their size.
