Question

Development of an embryo or seed without fertilization is called -

• A. Apomixis
• B. Anthesis
• C. Self-incompatibility
• D. Male sterility

Hint:

Apomixis ensures seed formation without fertilization. It is useful in agriculture for producing hybrid seeds without repeated crossing.

Answer 1

The Correct Option is A

Step 1: Recall the definition of apomixis.
Apomixis is an asexual mode of reproduction in which seeds are formed without fertilization. The embryo develops directly from somatic or gametophytic cells.

Step 2: Evaluate the options.
- Apomixis: Correct, it means seed/embryo formation without fertilization.
- Anthesis: Refers to the time of flowering, not seed formation.
- Self-incompatibility: A mechanism preventing self-fertilization in flowers.
- Male sterility: Inability to produce viable pollen, not related to apomixis.

Step 3: Conclusion.
Therefore, the correct answer is Apomixis.

Final Answer: \[ \boxed{\text{Apomixis is the development of seed without fertilization.}} \]
