- Accuracy of Selection
- a Variability of BV for a trait in the population. The greater the genetic variation, the greater the difference between superior and inferior animals.
- b Rate at which selected individuals replace existing parents in the population.
- c Correlation between true BV and predicted breeding value for a trait in a population.
- d Lists of genetic predictions, accuracy values, and other information for sires within a breed.
- e Selection based on performance above a certain level.
5 Multiple choice questions
- Ratio of individual performance compared to contemporary group mean.
- Traits for which individual animals have multiple performance records. (milk production, calf weaning weight)
- Indicator of the expected change in one trait relative to change in another trait in a population.
- Training, permanent injury, developmental programming.
- Calculate a combined "breeding value" based on several traits.
5 True/False questions
Temporary Environmental Effect → Training, permanent injury, developmental programming.
Selection Intensity → Calculate a combined "breeding value" based on several traits.
Independent Culling Levels → Set a minimum performance level for each trait being considered. Cull any animal that does not meet the standard for every trait.
Producing Ability → performance potential for a repeated trait in an individual.
Accurate Measurement → Correlation between true BV and predicted breeding value for a trait in a population.
