5 Matching questions

  1. adaptive evolution via natural selection
  2. reduced hybrid fertility
  3. evolution trap
  4. reduce
  5. intersexual selection
  1. a If there is no variation there is no oppurtunity for
  2. b a post-zygotic barrier where fertilizaiton occurs, but the hybrid is sterile and unable to reproduce (liger, mule, etc.)
  3. c mate choice, acts on traits that affect success on being chosen for mating by the opposite sex
