5 Matching questions

  1. Environmental Uniformity
  2. BLUP Models
  3. Truncation Selection
  4. Accurate Measurement
  5. Generation Interval
  1. a Reduce potential measurement error, use most precise measurement as possible.
  2. b Best Linear Unbiased Prediction. Enables large scale genetic evaluation.
  3. c Selection based on performance above a certain level.
  4. d Time required to replace on generation with the next generation. Shorter interval = faster rate of genetic change.
  5. e Manage animals to keep environmental effects as similar as possible across the population.

5 Multiple choice questions

  1. Multiple trait selection reduces selection intensity compared to selection for a single trait.
  2. Variability of BV for a trait in the population. The greater the genetic variation, the greater the difference between superior and inferior animals.
  3. Measure of the strength of the relationship between P and BV for a trait in a population.
  4. Indicator of the expected change in one trait relative to change in another trait in a population.
  5. Genetic value as a parent. Indication of potential to contribute to offspring.

5 True/False questions

  1. Repeated TraitsMeasure of the strength of the relationship between repeated records for a trait in a population.

          

  2. Independent Culling LevelsSet a minimum performance level for each trait being considered. Cull any animal that does not meet the standard for every trait.

          

  3. Gene Combination ValueImportant for individual performance

          

  4. Selection IndexMultiple trait selection reduces selection intensity compared to selection for a single trait.

          

  5. Permanent Environmental EffectTraining, permanent injury, developmental programming.
