Question

Reorganization of genetic material occurs during

• A. Metamorphosis
• B. Organogenesis
• C. Mitosis
• D. Meiosis

Answer 1

The correct option is D

Meiosis

The correct option is D

Explanation of the correct option:

Option D:

1. Meiosis consists of two divisions i.e, Meiosis I and Meiosis II.
2. Meiosis I is called reductional division (chromosome number is reduced to half) and Meiosis II is called equational division (the number of chromosomes remains the same).
3. During the pachytene (third stage of prophase I) phase of meiosis I, crossing over happens.
4. Crossing over leads to the recombination of genetic material.
5. The reorganization of genetic material occurs during meiosis.

Explanation of the incorrect option:

Option A:

Metamorphosis is the process of conversion from an immature form to an adult form.

Option B:

The formation and development of organs in living organisms is known as organogenesis.

Option C:

Mitosis is a process in which a parent cell divides into two daughter cells.

Final answer: The reorganization of genetic material occurs during Meiosis.
