- Environmental Uniformity
- BLUP Models
- Truncation Selection
- Accurate Measurement
- Generation Interval
- a Reduce potential measurement error, use most precise measurement as possible.
- b Best Linear Unbiased Prediction. Enables large scale genetic evaluation.
- c Selection based on performance above a certain level.
- d Time required to replace on generation with the next generation. Shorter interval = faster rate of genetic change.
- e Manage animals to keep environmental effects as similar as possible across the population.
5 Multiple choice questions
- Multiple trait selection reduces selection intensity compared to selection for a single trait.
- Variability of BV for a trait in the population. The greater the genetic variation, the greater the difference between superior and inferior animals.
- Measure of the strength of the relationship between P and BV for a trait in a population.
- Indicator of the expected change in one trait relative to change in another trait in a population.
- Genetic value as a parent. Indication of potential to contribute to offspring.
5 True/False questions
Repeated Traits → Measure of the strength of the relationship between repeated records for a trait in a population.
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.
Gene Combination Value → Important for individual performance
Selection Index → Multiple trait selection reduces selection intensity compared to selection for a single trait.
Permanent Environmental Effect → Training, permanent injury, developmental programming.
