The most commonly used method of classifying sheep is by what attribute?

• A. Wool
• B. Color
• C. Age
• D. Horn Type

Answer: (A)

Classifying sheep by the fleece they produce is the most practical and widely used method because wool type and quality directly drive breeding decisions, management, and market value. Producers group sheep by wool characteristics—such as fiber diameter, staple length, yield, and crimp—to align animals with the specific textile markets they aim to serve. This makes wool a defining trait for flock planning and product outcomes, more so than any other attribute.

Color, while noticeable, doesn’t consistently indicate wool quality or production purpose, and age or horn type are mostly about management or physical traits rather than a universal basis for classification.
