5 Multiple choice questions
- Selection based on performance above a certain level.
- Calculate a combined "breeding value" based on several traits.
- Ratio of individual performance compared to contemporary group mean.
- Lists of genetic predictions, accuracy values, and other information for sires within a breed.

5 True/False questions
Selection Intensity → Strictness of selection criteria.
Accurate Measurement → Reduce potential measurement error, use most precise measurement as possible.
Independent Culling Levels → Genetic value as a parent. Indication of potential to contribute to offspring.
Generation Interval → Time required to replace on generation with the next generation. Shorter interval = faster rate of genetic change.
Repeated Traits → Measure of the strength of the relationship between repeated records for a trait in a population.
