Transgenic Animals: Definition and Applications — NEET Biology
📚 Practice ConceptAnimals that have had their DNA manipulated to possess and express an extra (foreign) gene are known as transgenic animals. Transgenic rats, rabbits, pigs, sheep, cows and fish have been produced, although over 95 per cent of all existing transgenic animals are mice. Why are these animals being produced? How can man benefit from such modifications? Let us try and explore some of the common reasons:
Assertion (A): All existing transgenic animals are mice. Reason (R): Transgenic rats, rabbits, pigs, sheep, cows and fish have also been produced successfully.
View solution & NCERT explanation
Correct answer: C — If assertion is true but reason is false.
NCERT states “Transgenic rats, rabbits, pigs, sheep, cows and fish have been produced, although over 95 per cent of all existing transgenic animals are mice.” The Assertion removes the qualifier “over 95 per cent” making it false - not ALL transgenic animals are mice, just the vast majority. The Reason is true from NCERT, explicitly listing other transgenic animals that have been produced.
