The following questions could help answer the question above. What are the advantages of sexual reproduction? What are the disadvantages? How do traits selected by sexual selection and those selected by differential survival mix in an animal species? i.e. is it more important to mate or survive? Use specific examples to illustrate your point. Your answers should indicate an understanding of the mechanism behind natural selection. Propose a scenario where asexual reproduction would be favorable.arrow_forward
