Determine Whether Each Scenario Describes an Advantage or Disadvantage of Transgenic

Question 70

Matching

Determine whether each scenario describes an advantage or disadvantage of transgenic organisms.

Premises:
Transgenic pest-resistant crops may kill all vulnerable individuals, creating a population of pesticide-resistant pests.
Transgenic lab animals, such as mice, are engineered to carry human genes, allowing for better study of human diseases.
Farmers who plant transgenic herbicide-tolerant crops tend to use excess herbicides.
Transgenic pest-resistant crops may affect non-target pests.
Transgenic papayas resistant to the ring spot virus saved the papaya industry in Hawai'i.
Growing transgenic pest-resistant crops means less pesticide spraying.
All transgenic salmon are sterile females; therefore, they cannot breed with wild salmon populations.
Gene flow from transgenic herbicide-tolerant plants may create herbicide-tolerant weeds.
Transgenic salmon that grow faster than wild salmon may result in less pollution from salmon farms.
Transgenic animals, such as sheep and cows, produce medicinal proteins in their milk. This creates a larger and cheaper supply of some human drugs.
Responses:
Advantage
Disadvantage
