- A.It is a form of sexual reproduction that mimics asexual reproduction.
- B.It involves the production of seeds without fertilization, often through diplospory or apospory.
- C.It results in genetic variation due to the absence of meiosis.
- D.It is restricted to plants that do not produce flowers.
Show correct answer & step-by-step solution
Correct answer: B — It involves the production of seeds without fertilization, often through diplospory or apospory.
Solution
- Apomixis is a form of asexual reproduction that mimics sexual reproduction by producing seeds.
- It occurs without fertilization, meaning no syngamy or meiosis is involved in the formation of the embryo.
- Diplospory and apospory are common mechanisms where the embryo develops from a diploid cell.
- This process produces clones, so it does not result in genetic variation.
- Hence the answer is (B).
