5 Multiple choice questions
- Measure of the strength of the relationship between P and BV for a trait in a population.
- Ratio of individual performance compared to contemporary group mean.
- Genetic value as a parent. Indication of potential to contribute to offspring.
- Time required to replace on generation with the next generation. Shorter interval = faster rate of genetic change.
- Nutrition, track conditions, illnesses
5 True/False questions
Independent Culling Levels → Set a minimum performance level for each trait being considered. Cull any animal that does not meet the standard for every trait.
Selection Intensity → Multiple trait selection reduces selection intensity compared to selection for a single trait.
Repeatability → Measure of the strength of the relationship between P and BV for a trait in a population.
Environmental Uniformity → Measure of the strength of the relationship between repeated records for a trait in a population.
Rate of Genetic Change → Rate at which selected individuals replace existing parents in the population.
