Meiosis is the cell division of two daughter cells that are identical to the parent cell. Meiosis happen in organisms such as plants.

Germ cells, specifically spermatocytes in males and oocytes in females, undergo meiosis to produce gametes (sperm and egg cells) with half the number of chromosomes as the parent cell. This is essential for sexual reproduction.

In meiosis I, homologous chromosomes are separated into different daughter cells, which is a crucial event that reduces the chromosome number by half, leading to haploid cells. This process involves the pairing and recombination of homologous chromosomes during prophase I, which does not occur in meiosis II. In meiosis II, the focus is on separating sister chromatids, similar to what occurs in mitosis, without any further reduction in chromosome number.

Yes, meiosis results in the formation of four haploid cells from one diploid cell, not just two. The process involves two rounds of cell division—meiosis I and meiosis II. In meiosis I, homologous chromosomes are separated, leading to two haploid cells, and in meiosis II, the sister chromatids are separated, resulting in a total of four haploid gametes.
The product of meiosis is four genetically distinct haploid cells, each containing half the number of chromosomes as the original diploid cell. This process occurs in two rounds of cell division, meiosis I and meiosis II, and is essential for sexual reproduction, as it produces gametes (sperm and eggs) in organisms. The genetic variation among the resulting cells is a result of crossing over and independent assortment during meiosis.
Mitosis and meiosis are both processes of cell division, but they serve different purposes and have distinct outcomes. Mitosis results in two genetically identical daughter cells and is used for growth, repair, and asexual reproduction. In contrast, meiosis produces four genetically diverse daughter cells, each with half the chromosome number, and is essential for sexual reproduction. While both processes involve similar stages, they differ significantly in their final results and mechanisms.
Mitosis and meiosis are both processes of cell division, but they serve different purposes and have distinct mechanisms. Mitosis results in two genetically identical daughter cells and is used for growth, repair, and asexual reproduction, while meiosis produces four genetically diverse gametes (sperm or eggs) for sexual reproduction. Both processes involve phases like prophase, metaphase, anaphase, and telophase, but meiosis includes two rounds of division and introduces genetic variability through crossing over and independent assortment. Thus, while they share some similarities, their outcomes and functions are fundamentally different.
