20. Consider the following statements –
1. Asexual reproduction preserves the genetic information, while sexual reproduction permits variation.
2. Use of gene cloning and gene transfer allows us to isolate and introduce only one or a set of desirable genes without introducing undesirable genes into the target organism.
Correct answer code is:

The correct option is C Both 1 and 2
Asexual reproduction preserves the genetic information, while sexual reproduction permits variation.
Traditional hybridisation procedures used in plant and animal breeding, very often lead to inclusion and multiplication of undesirable genes along with the desired genes.
The techniques of genetic engineering which include creation of recombinant DNA, use of gene cloning and gene transfer, overcome this limitation and allows us to isolate and introduce only one or a set of desirable genes without introducing undesirable genes into the target organism.
