What type of cell division results in four haploid cells from one diploid cell?

Meiosis is the type of cell division that results in four haploid cells from one diploid cell. This process is essential for sexual reproduction and occurs in two main stages: Meiosis I and Meiosis II. During Meiosis I, homologous chromosomes are separated, allowing for genetic variation through crossing over and independent assortment. Each of the two resulting cells is haploid, meaning they contain one set of chromosomes. In Meiosis II, these haploid cells undergo a division similar to mitosis, where sister chromatids are separated, ultimately producing four haploid daughter cells. These haploid cells are gametes, such as sperm and eggs in animals, which can combine during fertilization to form a diploid zygote, restoring the chromosome number in the organism.
