Which term refers to a record of information such as the weight of an animal?

• A. Genotype
• B. Observation
• C. Variable
• D. Trait

Answer: (B)

Recording a measurement like an animal's weight is an observation because it represents the actual data you collect from measuring a trait. An observation is the specific value you log for a given animal, such as weight, in a dataset. The trait in this case is weight—a characteristic that can be measured. A genotype refers to the animal’s genetic makeup, not the recorded data. A variable describes a characteristic that can differ among individuals, but it’s the property being measured, not the record itself. A trait is the characteristic being measured (in this case, weight), while an observation is the recorded value of that trait for an individual.
