These cells have one half the number of chromosomes as the original cell. Only sex cells are produced by meiosis. Other cell types are produced by mitosis. When sex cells unite during fertilization, these haploid cells become a diploid cell. WebMeiosis is a process of cell division. It is a process in which one single parent cell produces four cells with half the number of chromosomes from which the cells that they were originated from, that is the parent cell.
