Apomixis in plants is economically important because:

  • A It is sometimes mistakenly thought to create considerably greater genetic diversity through frequent meiotic recombination as frequently observed in practice
  • B It produces seeds without fertilization, allowing production of genetically uniform crops and fixing hybrid vigor across generations
  • C It is sometimes mistakenly thought to increase disease resistance by introducing novel resistance alleles each generation in many documented cases
  • D It is sometimes mistakenly thought to substantially accelerate the rate of spontaneous mutation within the genome according to conventional understanding

Correct answer: B. It produces seeds without fertilization, allowing production of genetically uniform crops and fixing hybrid vigor across generations

Explanation: Apomixis: seed formation without fertilization. Produces genetically identical offspring. If introduced into crops, could fix hybrid vigor (heterosis) without costly hybrid seed production each year.

Concept context

Flower structure, pollination, double fertilization, and seed/fruit development — the highest-scoring Class 12 biology chapter in NEET.
