Question

Offsets are produced by

• A. Meiotic divisions
• B. Parthenocarpy
• C. Mitotic divisions
• D. Parthenogenesis

Answer 1

The Correct Option is C

Offsets are produced by mitotic divisions. Let's explore why this is the correct answer and rule out the other options:

1. Understanding Offsets:
   • Offsets are vegetative propagules, which means they are structures that enable plants to reproduce asexually.
   • They are small structures or clones that detach from the parent plant and can develop into new independent plants.
   • Since they are clones, they are genetically identical to the parent because they originate from mitotic divisions.
2. Mitotic Divisions:
   • Mitosis is a type of cell division that results in two daughter cells that are identical to the parent cell.
   • This ensures that the offsets, being products of mitotic division, maintain the same genetic material as the parent plant, allowing uniform propagation.
3. Eliminating Other Options:
   • Meiotic Divisions:
     • Meiosis leads to the production of gametes and has genetic variation as it involves recombination and reduction division.
     • This is not the method by which offsets are created, as offsets are asexual and identical to the parent.
   • Parthenocarpy:
     • This is the development of fruit without prior fertilization, typically seen in virgin fruits like bananas.
     • It does not produce offsets.
   • Parthenogenesis:
     • Parthenogenesis is the development of an organism from an unfertilized ovum, common in some insects and plants.
     • It is not directly related to the creation of offsets, as offsets are not derived from the ovum.

Conclusion: Therefore, mitotic divisions are responsible for the production of offsets, as they ensure the offspring are genetically identical to the parent plant. This makes option "Mitotic divisions" the correct answer.
