In the process of meiosis-2, four nuclei are formed from two nuclei. In this process the number of chromosomes is equal. Hence it is called a division analogous to mitosis. It is divided into four states. Prophase-II, Metaphase-II, Anaphase-II and Telophase-II.
1. Prophase-2: Dehydration of water occurs in the chromosomes in Prophase-2. Chromosomes increase in dye capacity. Chromosomes become shorter and thicker. At the end of this stage, the nuclear envelope and nucleolus disappear.
2. Metaphase-2: In metaphase-2, the chromosomes become thicker and shorter. Spindle machine is created. Chromosomes are located at the equator and attached to traction fibers. At the end of this phase, the centromeres of the chromosomes divide.
3. Anaphase-2: In anaphase-2, the centromeres of the chromosomes are completely separated. Polar movement of chromatids occurs due to contraction of traction fibers and elongation of stem bodies. During polar movement, the centromere is the leader and the armature is the follower. When the chromosomes reach the poles, they look like the letters V, L, J or I.
4. Telophase-2: Telophase-2 is the last stage of meiosis-2. At this stage the chromosomes are fixed at opposite poles. Chromosome water hydration occurs. Chromosomes decrease in capacity to hold dyes. Chromosomes are narrow, long and fuzzy. The nuclear membrane and nucleolus appear. As a result, two nuclei are formed at both ends.
