- Generation Interval
- Permanent Environmental Effect
- BLUP Models
- Contemporary Grouping
- a Time required to replace on generation with the next generation. Shorter interval = faster rate of genetic change.
- b Grouping animals that experience similar environmental effects.
- c Training, permanent injury, developmental programming.
- d Measure of the strength of the relationship between repeated records for a trait in a population.
- e Best Linear Unbiased Prediction. Enables large scale genetic evaluation.
5 Multiple choice questions
- -influences resemblance among relatives
-influences accuracy of selection and rate of genetic change
- Response due to selection
- Genetic value as a parent. Indication of potential to contribute to offspring.
- Reduce potential measurement error, use most precise measurement as possible.
- Multiple trait selection reduces selection intensity compared to selection for a single trait.
5 True/False questions
Replacement Rate → Rate at which selected individuals replace existing parents in the population.
Gene Combination Value → Important for individual performance
Environmental Uniformity → Manage animals to keep environmental effects as similar as possible across the population.
Trait Ratios → Calculated using covariance, a measure of how two traits or values vary together in a population.
Independent Culling Levels → Genetic value as a parent. Indication of potential to contribute to offspring.
