Besides the most frequent deep black or dark brown, what other colorations might yaks exhibit?
Answer
Lighter brown, gray, or even white markings
While the majority of yaks observed in their high-altitude ranges present coloration in deep black or dark brown shades, coat color is not universally uniform across the species. Variation exists among individuals, demonstrating a broader spectrum of natural coloring. Some yaks can be seen exhibiting lighter brown hues, distinct gray coloring, or even displaying patches of white markings within their overall coat composition.
