Question

The number of chromosomes is reduced to half during

• A. Mitosis
• B. Meiosis II
• C. Meiosis I
• D. Fertilisation

Answer 1

Answer: (C)

Meiosis I

Meiosis is the type of cell division by which gamete cells (eggs and sperms) are produced. Meiosis involves two successive nuclear divisions and one cytoplasmic division that produce four haploid cells. The first division (meiosis) is the reductional division during which number of chromosomes is reduced to half. The second division (meiosis II) separates the chromatids. It is called equational division as chromosomes number remains the same as produced after meiosis I.

So, the correct answer is 'Meiosis I'.
