In questions 4, 5, 6 and 7 above you calculated response to selection for two different scenarios two different ways. You should have different answers for each! Looking at those answers, what contributed to the difference in response between selecting 20% and 10%? Also, comparing the selection based on the data to the selection based on population variability, what contributed to the difference in response between the two situations? Question 8 options: 1) 1) Reducing the proportion selected decreased the selection response because the average phenotype of the selected group changed. 2) The selection response was different between using the data and using the variability and assuming normality. This is due to the fact that the actual phenotypes are not normally distributed so assuming normality to use σp wasn't really a valid assumption. 2) 1) Reducing the proportion selected increased the selection response because the average phenotype of the selected group increased. 2) The selection response was different between using the actual data and using the variability and assuming normality. This is due to the fact that the actual phenotypes are not normally distributed so assuming normality to use σp wasn't really a valid assumption. 3) 1) Reducing the proportion selected increased the selection response because the average phenotype of the selected group increased. 2) The selection response was the same when using the data and using the variability and assuming normality. This is due to the fact that the actual phenotypes are normally distributed so assuming normality to use σp wasn't really a problem.
