1. Traits don't necessarily have to be passed on from parent to offspring for natural selection to act on them; traits that are environmentally acquired during the life time of an individual (such as practicing to become very strong or very fast) can also be acted upon by natural selection. Select one: True or False

2.Within the same species and even within the same population, not all individuals are the same. They vary in size, shape or other traits.

4) Because individuals survive, mate and reproduce rather than individual traits, we expect that many traits in an organism will be phenotypically and genetically correlated. List two of the possible evolutionary outcomes that can occur when selection operates on genetically correlated traits (1), and explain why these outcomes occur (3). Give an actual, not hypothetical, example for one of them using a real organism (1).
