- b Response due to selection
- c Calculate a combined "breeding value" based on several traits.

- e Grouping animals that experience similar environmental effects.
5 Multiple choice questions
- Set a minimum performance level for each trait being considered. Cull any animal that does not meet the standard for every trait.
- Strictness of selection criteria.
- Multiple trait selection reduces selection intensity compared to selection for a single trait.
- Lists of genetic predictions, accuracy values, and other information for sires within a breed.
- Rate at which selected individuals replace existing parents in the population.
5 True/False questions
Tandem Selection → Selection based on performance above a certain level.
Correlation → Indicator of the expected change in one trait relative to change in another trait in a population.
Accuracy of Selection → Selection based on performance above a certain level.
Characteristics of Repeatability → -not fixed, varies across populations and environments
-used for making culling decisions
Gene Combination Value → Variability of BV for a trait in the population. The greater the genetic variation, the greater the difference between superior and inferior animals.
