Bollworms raised for decades in a lab without exposure to Bt were ___ while those fed Bt were ___.

Question

Quizplus · Accepted Answer

The Bt gene confers resistance to bollworms. Bollworms that were not exposed to Bt in the lab would not have developed any resistance, so they would be susceptible to it. Those that were fed Bt in the lab would have developed resistance to it. Therefore, the bollworms raised in the lab without exposure to Bt would have the rr genotype (susceptible) while those fed Bt would have developed the RR genotype (resistant).
