Meiosis is the process by which a regular diploid body cell divides and becomes 4 haploid gametes. It consists of two stages: Meiosis I and Meiosis II. Meiosis I is the first division of cells and Meiosis II is the second. This process is generally similar to regular Mitosis with a few differences that effect the end products.
Haploid cells are produced by meiosis. During meiosis, the chromosome number is halved from the diploid number to the haploid number. Similar to mitosis, in meiosis also, DNA replication takes place in the parent cell during the interphase. After this, two cycles of nuclear divisions and cell divisions take place.ince each gamete has only one set of chromosomes, the end resulting zygote will have only two sets of chromosomes. That is the zygote becomes diploid. If the gametes were not haploid cells, the result at the end would be a zygote with four sets of chromosomes.
