Consider the above graphs showing the midparent values against the midoffspring values. What would you expect to happen to the mean phenotype value of the population, if only the parents with the highest trait values were allowed to breed (orange dots)? Use terms like 'strong increase', 'weak increase', 'no change'. Explain your answer.

Consider the above graphs showing the midparent values against the midoffspring values. What would you expect to happen to the mean phenotype value of the population, if only the parents with the highest trait values were allowed to breed (orange dots)? Use terms like 'strong increase', 'weak increase', 'no change'. Explain your answer. 4. Why is sexual selection a form of natural selection? Do natural selection and sexual selection always act in the same way? 5. What is an evolutionary constraint? How does their occurrence help answer the question whether all traits are adaptive? 6. Read the article by Gould and Lewontin: 'The Spandrels of San Marco and the Panglossian Paradigm'. a. What is the most important criticism the authors put forward? b.
