Give two examples of traits that are influenced by sexual selection and how they differ between males and females.

Consider the roles of different types of selective pressure. Part A: Compare and contrast sexual selection, artificial selection, and natural selection. Part B: Give examples of traits that may be favored in sexual selection, artificial selection, and natural selection. For each, explain if the trait would be favored by one type of selection but selected against by another type of selection.
