What is a Palomino horse characterized by?

A Palomino horse is defined by its distinctive coat color, which features a light tan or golden body complemented by a creamy or white mane and tail. This unique coloration arises from a specific genetic dilution of the chestnut coat color gene, resulting in shades that can range from a deep gold to a very light cream. The striking contrast between the body color and the mane and tail is a hallmark of the breed, making Palominos easily recognizable and sought after.

While other choices describe different types of horses or color patterns, they do not fit the established characteristics of a Palomino. The traits of tone and mane color in option B distinctly encapsulate what makes a Palomino, highlighting the importance of recognizing specific genetic attributes in horse breeds.
