What is blue eyes an example of in genetics?

• A. Character
• B. Phenotype
• C. Trait
• D. Genotype

Answer: (C)

Blue eyes represent a specific version of a characteristic that can be observed in individuals, making it a clear example of a trait in genetics. Traits are distinct features or properties that can vary among individuals, and they can be influenced by genetic and environmental factors. In this context, "blue eyes" refers specifically to the observable feature (the eye color) rather than the underlying genetic makeup.

To further clarify, a character would be the broader category that encompasses all types of eye colors, while a phenotype describes the physical manifestation of a trait, which, in this case, would include blue eyes as one possible expression of the eye color character. The genotype refers to the specific genetic makeup responsible for this coloration, but when we talk about blue eyes, we are focusing on what is visibly expressed rather than the genetic basis for it. Thus, identifying blue eyes as a trait underscores its specific, observable nature within the broader spectrum of genetic characteristics.
