  3. Producing Ability
  4. Accuracy of Selection
  5. BLUP Models
  1. a Manage animals to keep environmental effects as similar as possible across the population.
  2. b Select for one trait at a time. After reaching the target for the first trait begin selecting for the next trait.
  3. c performance potential for a repeated trait in an individual.
  4. d Best Linear Unbiased Prediction. Enables large scale genetic evaluation.
  5. e Correlation between true BV and predicted breeding value for a trait in a population.

5 Multiple choice questions

  1. Selection based on performance above a certain level.
  2. Calculate a combined "breeding value" based on several traits.
  3. Ratio of individual performance compared to contemporary group mean.
  4. Lists of genetic predictions, accuracy values, and other information for sires within a breed.
  5. Rate at which selected individuals replace existing parents in the population.

5 True/False questions

  1. Selection IntensityStrictness of selection criteria.


  2. Accurate MeasurementReduce potential measurement error, use most precise measurement as possible.


  3. Independent Culling LevelsGenetic value as a parent. Indication of potential to contribute to offspring.


  4. Generation IntervalTime required to replace on generation with the next generation. Shorter interval = faster rate of genetic change.


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