Questions and Answers

What is one way to slow the rate at which genes for pesticide resistance spread?

  • Providing refuges where non-resistant insects thrive (correct)
  • Increasing the genetic variation of pests
  • Providing a large amount of pesticides
  • Breeding pesticide-resistant insects

  • By helping them improve crop disease resistance (correct)
  • By reducing the nutritional value of crops
  • By allowing them to breed pesticide-resistant pests
  • By increasing the use of pesticides
  • What is a consequence of inbreeding in small populations?

  • Improved population survival
  • Increased genetic variation
  • Inbreeding depression (correct)
