The survival of the 2 percent of the population is due to the presence of a gene obtained from other species. This gene must be responsible for developing resistance in the insects, against the insecticide that was used by the farmer. The gene got incorporated in only 2% of the insects and therefore, they survived and rest of them were susceptible to the insecticide and thus, died.
Right answer is c.
DNA is in the form of antiparallel strands twisted as a double helix.
The development of resistance to the disease has taken different courses. In Australia, the virus initially killed rabbits very quickly – about 4 days after infection. This gave little time for the infection to spread. However, a less virulent form of the virus then became prevalent there, which spread more effectively by being less lethal. In Europe, many rabbits are genetically resistant to the original virus that was spread. The survival rate of diseased rabbits has now increased to 35%, while in the 1950s it was near zero.[15]
