Solution
The correct option is C Both statements I and II are correct
Traditional hybridisation is a form of intentional human-mediated hybridisation which involves the crossing of individuals of different species (interspecific hybridisation) or genetically divergent individuals from the same species (intraspecific hybridisation). These procedures used in plant and animal breeding, very often lead to inclusion and multiplication of undesirable genes along with the desired genes.
Transgenic plants can be made by rDNA technology using DNA from different species like bacteria, other plants and animals. rDNA technology is faster in comparison to traditional breeding and enables the gene of interest to be precisely identified, delivered and expressed in the transgenic plant.
The transgenic plant becomes more tolerant to abiotic stress, insects, or post-harvest losses. These factors make rDNA/transgenic technology more advantageous as compared to traditional hybridisation.
An example of a transgenic plant is Bt cotton. It was genetically modified to provide resistance to plants against insects without the need for insecticides (Bio - pesticide). The gene from Bacillus thuringiensis that is responsible for production of Cry protein (insecticidal protein) was identified, isolated and then transferred into the plant.
