5 Matching questions

  1. Replacement Rate
  2. Producing Ability
  3. Sire Summaries
  4. BLUP Models
  5. Characteristics of Repeatability
  1. a Best Linear Unbiased Prediction. Enables large scale genetic evaluation.
  2. b Rate at which selected individuals replace existing parents in the population.
  3. c Lists of genetic predictions, accuracy values, and other information for sires within a breed.
  4. d -not fixed, varies across populations and environments
    -used for making culling decisions
  5. e performance potential for a repeated trait in an individual.

5 Multiple choice questions

  1. Measure of the strength of the relationship between P and BV for a trait in a population.
  2. Ratio of individual performance compared to contemporary group mean.
  3. Genetic value as a parent. Indication of potential to contribute to offspring.
  4. Time required to replace on generation with the next generation. Shorter interval = faster rate of genetic change.
  5. Nutrition, track conditions, illnesses

5 True/False questions

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

          

  2. Selection IntensityMultiple trait selection reduces selection intensity compared to selection for a single trait.

          

  3. RepeatabilityMeasure of the strength of the relationship between P and BV for a trait in a population.

          

  4. Environmental UniformityMeasure of the strength of the relationship between repeated records for a trait in a population.

          

  5. Rate of Genetic ChangeRate at which selected individuals replace existing parents in the population.
