In breeding terms, which description best defines a population?

• A. A single animal
• B. An environment
• C. A breed
• D. A set of observations

Answer: (D)

The population in this context is the set of observations collected from individuals for a trait or set of traits. This is the data you analyze to estimate genetic parameters and breeding values, so it defines the actual units of analysis for the study. A single animal is just one data point, not the whole group; the environment is a condition that influences traits rather than the group being studied; a breed is a defined group with a common gene pool, but it isn’t the data set you analyze in isolation. A set of observations best captures the idea of the population you’re using to draw inferences in breeding analyses.
