  10. 11. FEATURE <ul><li>Any general structure, characteristic, or behavior of an organism </li></ul><ul><ul><li>Wings, fur, pattern, color and migration </li></ul></ul><ul><ul><li>ALL have this </li></ul></ul>
  11. 12. TRAIT <ul><li>The specific expression of a feature in an individual </li></ul><ul><ul><li>Wing length, number of spots, thickness of fur, intensity of color, timing of migration </li></ul></ul><ul><ul><li>SOME have this </li></ul></ul>
  12. 19. VARIATION <ul><li>When there are several traits for the same feature in a population </li></ul><ul><ul><li>One example are the 3 different colors exhibited by walking sticks </li></ul></ul><ul><li>Allows a population to survive even if the environment changes </li></ul>
