| Study and Review Hint for question 8 Review section 8.5, Predicting the Evolutionary Response to Selection. The biological relationship between the response to selection and heritability and the selection differential should be clear from your basic understanding of how natural selection works. Selection can only work on heritable variation, so the higher the heritability of a trait, the greater is its potential to respond to selection. Similarly, the more strongly selection acts, the more strong the response should be. |
