Question

Assertion: Traditional hybridisation leads to the inclusion and multiplication of undesirable along with the desired genes

Reason: Recombinant DNA technology allows insertion of the desired gene only into the target organisms

• A. Both assertion and reason are true and the reason is a correct explanation of the assertion
• B. Both assertion and reason are true but the reason is not a correct explanation of the assertion
  
• C. Assertion is true but the reason is false
• D. Both assertion and reason are false

Answer 1

The correct option is B Both assertion and reason are true but the reason is not a correct explanation of the assertion


Traditional biotechnology refers to the techniques of using living organisms to produce new or modified products which are useful for human beings. Examples of traditional biotechnology are selective breeding in animals and plants for desired characteristics, in cheese, bread, beer, and wine production. The drawback of traditional biotechnology is that during selective breeding undesired characters along with desired ones are passed to the offspring because it involves no technique to inhibit the inclusion and multiplication of undesired characters.
Recombinant DNA technology overcomes the setback of traditional biotechnology and allows the insertion of the desired gene only into the target organisms using various enzymes.
Thus, both assertion and reason are true but the reason is not a correct explanation of the assertion.
