Full Answer

These traits can strongly influence the survival of an organism. Acquired traits can cause an organism with a genetic disadvantage to out-compete another. An example of an acquired trait is a bodybuilder's large muscles. They were acquired by lots of exercise and not genetics, so the offspring of the body builder are no more likely to have large muscles than other offspring.
