5 Matching questions

  1. Producing Ability
  2. Rate of Genetic Change
  3. Contemporary Grouping
  4. Regression
  5. Selection Index
  1. a Indicator of the expected change in one trait relative to change in another trait in a population.
  2. b Response due to selection
  3. c Calculate a combined "breeding value" based on several traits.
  4. d performance potential for a repeated trait in an individual.
  5. e Grouping animals that experience similar environmental effects.

5 Multiple choice questions

  1. Set a minimum performance level for each trait being considered. Cull any animal that does not meet the standard for every trait.
  2. Strictness of selection criteria.
  3. Multiple trait selection reduces selection intensity compared to selection for a single trait.
  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. Tandem SelectionSelection based on performance above a certain level.

          

  2. CorrelationIndicator of the expected change in one trait relative to change in another trait in a population.

          

  3. Accuracy of SelectionSelection based on performance above a certain level.

          

  4. Characteristics of Repeatability-not fixed, varies across populations and environments
    -used for making culling decisions

          

  5. Gene Combination ValueVariability of BV for a trait in the population. The greater the genetic variation, the greater the difference between superior and inferior animals.
