te sides of the cell. However, the centromeres do not split, ensuring that the gamete will get only chromosome from each homologous pair. Telophase I breaks down everything in the reverse order that it happened,first the spindle is broken down, the chromosomes uncoil, and the cytoplasm divides to yield two new cells. Even though, each cell has the diploid amount of genetic information, another division is needed because each chromosome is still doubled.In meiosis II, some cells have a short interphase in which the chromosomes do not replicate, in some other organisms, the cells go from late anaphase of meiosis I, to metaphase II, skipping telophase I, the short interphase, and prophase II. During Prophase II, the spindle forms in both of the newly born cells and the spindle fibers attach to the chromosomes. During metaphase II the chromosomes are yet again pulled to the equator of the cell. Anaphase II begins as soon as the centromere of each sister chromatid splits allowing them to move towards their poles. In telophase II, the nuclei reform, the spindles break down, and cytokinesis occurs.The end product of meiosis is very similar to Mendels experiment in that there are sixteen different combinations for a zygote. Although meiosis usually goes ok, sometimes there is a mistake and chromosomes dont seperate correctly. This is called nondisjunction. There are three types of nondisjunction, Trisomy- when a gamete with an extra chromosome is fertiized with a normal gamete. Monosomy- when a gamete with one chromosome is missing and is then fertilized by normal gamete. And Trioloidy- where both zygotes have an extra chromosome.Reproduction is as essential to a species as food, water, or shelter. If a species cannot reproduce anymore, that species will eventually become extinct. There are many means of reproduction but primarily only two: asexual and sexual. In asexual reproduction, One organism gives a part or its whole self, in order to giv...
