How many meiotic and mitotic divisions are required to form two male gametes from PMC?
Two meiotic divisions and two mitotic divisions are required to form two male gametes from PMC.
Meiotic Division
- Meiosis is a type of cell division that reduces the number of chromosomes in the cell by half.
- It involves two successive divisions, meiosis I and meiosis II, each consisting of prophase, metaphase, anaphase, and telophase stages.
- Meiosis I separates homologous chromosomes, resulting in two haploid daughter cells with replicated chromosomes.
- Meiosis II separates sister chromatids, resulting in four haploid daughter cells with unreplicated chromosomes.
- In the case of male gametes, meiosis occurs in the primary spermatocyte, which is the product of one mitotic division of the spermatogonium.
- Meiosis I produces two secondary spermatocytes, which then undergo meiosis II to produce four spermatids.
Mitotic Division
- Mitosis is a type of cell division that results in two daughter cells with the same number of chromosomes as the parent cell.
- It involves one division consisting of prophase, metaphase, anaphase, and telophase stages.
- In the case of male gametes, mitosis occurs in the spermatids, which are the product of meiosis II.
- The two spermatids resulting from each secondary spermatocyte undergo mitotic division to produce four spermatids.
- Each spermatid then undergoes further differentiation to become a mature sperm cell.
Conclusion
Therefore, it takes one mitotic division and two meiotic divisions to produce two mature sperm cells from a primary spermatocyte (PMC).

In order to form microspore tetrad. 1meiosis is required. each cell of tetrad undergoes 2 mitotic division to form 2 male gametes. actually microsporogenesis means formation of microspore or pollen grains. so 1 meiotic divine is involved for the formation of 4 microspore.
