Study Notes
- Meiosis I begins with prophase I and ends with the separation of maternal and paternal chromosomes.
- In meiosis I, each daughter cell receives two copies of either the maternal or paternal chromosome.
- The first meiotic division is called a reductional division because it reduces the number of chromosomes from diploid to haploid.
- Meiosis II is an equational division that separates chromatids and yields four haploid cells.
- The cytoplasm may not be evenly distributed among the four cells.
- In males, meiosis produces four identical gametes that develop into functional sperm.
- In females, meiosis produces one oocyte and three polar bodies.
- If fertilization takes place, the oocyte completes meiosis II, yielding an ovum.
- Spermatogenesis is the process of meiosis in males.
- Oogenesis is the production of female oocytes.
