Answer:
C
Step-by-step explanation:
Cloning reproduces the exact same crops identical to the plant from which the cloning tissue was taken. While this has the capacity to preserve the purity of a breed of plants with desired characteristics, it can also have undesirable effects. Without sexual reproduction, there would be no genetic variability of the crop. This means the plant will hardly adapt to environmental changes and could go extinct if not further genetically engineered.
