Meiosis is a biological phenomenon involving two successive divisions of cells. Meiosis results in the formation of four daughter cells which are haploid (the number of chromosomes is halved from the parent cell). The daughter cells have different genetic material from the parent cell due to the recombination of chromosomes. Consequently, it forms only germ cells i.e. eggs and sperms. This phenomenon takes place in organisms like animals, plants, and fungi. Prophase I is known to be the longest phase of meiosis.
The crossing over of chromosomes through which the genetic material is shuffled takes place during this phase. These chromosome pairs form an equatorial plate in metaphase I. In anaphase I, the sister chromatids formed in metaphase I tend to move together to the same pole are these chromatids then get separated from each other in anaphase II. In the telophase, the cell divides into two. The steps of meiosis II two are exactly the same as those of mitosis.
