-
A.
Increased biodiversity
-
B.
Unintended effects on non-target species
-
C.
Improved crop resilience
-
D.

-
A.
Bioremediation
-
B.
Phytoremediation
-
C.
Plant breeding
-
D.
Plant taxonomy

Q. Which of the following is NOT a concern associated with the use of GMOs?
-
A.
Potential allergenicity
-
B.
Gene transfer to non-target species
-
C.
Increased crop resilience
-
D.

Q. Which of the following is NOT a method of plant biotechnology?
-
A.
Gene cloning
-
B.
Tissue culture
-
C.
Traditional breeding
-
D.
