Genetic Engineering Over Hybridization — NEET Biology
📚 Practice ConceptYou probably appreciate the advantages of sexual reproduction over asexual reproduction. The former provides opportunities for variations and formulation of unique combinations of genetic setup, some of which may be beneficial to the organism as well as the population. 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.
Assertion (A): Genetic engineering techniques overcome limitations of traditional breeding methods. Reason (R): Traditional hybridization often includes undesirable genes along with desired ones.
View solution & NCERT explanation
Correct answer: B — If both assertion and reason are true but reason is not the correct explanation of the assertion.
NCERT states genetic engineering “overcome this limitation and allows us to isolate and introduce only one or a set of desirable genes” making the Assertion true. NCERT also states “Traditional hybridisation procedures used in plant and animal breeding, very often lead to inclusion and multiplication of undesirable genes along with the desired genes” making the Reason true. However, the Reason describes the problem that genetic engineering solves, but doesn’t explain HOW genetic engineering overcomes it.
