Which traits affect the appearance of an organism, such as flower color?

• A. Physiological traits
• B. Morphological traits
• C. Genetic traits
• D. Behavioral traits

Answer: (B)

Morphological traits are those that directly relate to the form and structure of an organism, including features such as flower color, leaf shape, and overall body structure. These traits are often visible and can be assessed based on physical characteristics. For example, in plants, the color of flowers is determined by the genetic makeup that influences pigment production, resulting in observable differences among species or varieties. While physiological traits refer to the internal processes that affect an organism's function (like metabolic rates or nutrient absorption), genetic traits encompass the entire range of inherited characteristics, which include morphological traits as a subset. Behavioral traits, on the other hand, pertain to the actions and reactions of an organism in response to environmental stimuli and do not directly dictate appearance. Therefore, the correct choice is morphological traits, as they specifically pertain to the outward physical attributes of organisms, such as flower color.
