Evaluation of the breeding program
22 important questions on Evaluation of the breeding program
What is, apart from genetic progress that has been achieved, another important aspect that needs to be evaluated in breeding programs?
How is it possible to get a good approximation of the genetic improvement accross generation?
Why is it covenient in livestock to look at the average EBV per birth year rather than per generation?
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
What exactly requires evaluation in the EBV?
How can realised genetic improvement be determined?
What is a genetic trend?
What if there is an incease in EBV?
What do you do when the realized genetic response deviates substantially from the predicted genetic response?
What can be a reason for not meeting the expected response to selection?
What are the main reasons for the occurence of a selection limit?
- Opposing natural selection through reduced ferility or oven mortality
- Limiting environment to express potential
What can be reasons for deviations from expected genetic trend?
What is genotype by environment (GxE)?
What is the reaction norm?
What does a reaction norm represent?
What do non-prallel reaction norms of genoypes indicate?
What do two environments require?
What is a reason for correlation?
What is a pleiotropic effect of a gene?
What are the reasons for genetic correlation to excist?
- Pleiotropic effect
- Conflicting resource allocation
What is the cost of avoiding correlated responses?
Where does multi-trait selection to avoud undesirable correlated responses lead to?
What is also important in predicting the future?
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
