  reproduce.

24

• Circle the best answer.
• Natural selection acts on ( acquired / inherited
  ) traits.
• Natural selection refers to the ability of an
  organism to survive and reproduce- therefore,
  offspring inherit the parents traits.
• Acquired traits refer to a trait that is not
  dependant upon inheritance but is usually
  affected by the environment. We discussed this
  during genetics. You may inherit the ability to
  speak but you acquire the ability to speak
  English because you live with a family that

  were bred to produce offspring that would be able
  to retrieve birds for hunting.

  dark colored lava flow is camouflaged from the
  owl so dark colored pocket mice are more likely
  to survive and reproduce than white colored
  pocket mice.
