Resistance against Manduca sexta was conferred by transferring _____________ genes using transgenics.
ABt
BCpT I
CCry III
DLambda A I
Answer:
A. Bt
Read Explanation:
Bt (Bacillus thuringiensis) genes.
Bt genes encode for a toxin that is poisonous to certain insect pests, including the tobacco hornworm (Manduca sexta).
By transferring Bt genes into plants using genetic engineering (transgenics), scientists have been able to create crops that are resistant to certain insect pests.
This technology has been widely used to develop insect-resistant crops, such as Bt corn and Bt cotton.
