The opposite process would be fertilization, which is the union of the egg and sperm to restore the 2n number resulting to a zygote, the first cell formed by fertilization. The process of meiosis involves two cycles of division, including a diploid mother cell dividing and then dividing again to form 4 haploid daughter cells. These can be subdivided into four distinct phases. There are some unique points that distinguish meiosis from mitosis. In the prophase , replicated homologous chromosomes begin to pair up with one another leading to crossing-over which called tetrads. In the anaphase , the homologous chromosomes are separated, moving to opposing poles from the equator, becoming haploid. The process of second division of meiosis is basically as same as mitosis. As a result, four new unreplicated haploid gametes are created. The most important thing of meiosis's process is the fact that chromosomes gametes are created....
