Genes are what parent passes on to their off spring. The reason that the off spring don’t look identical to the parent is due to a process called crossing over during meiosis.. Meiosis creates new cells that contain different data than that of the parent due to the genes getting shuffled around by cross linking. The chromatids which are parts of the chromosome cross over bits of data making the new cell unique from the parental chromosome. Dividing this way will ensure that the genes will be randomly selected and different from the parent chromosomes, which will then be passed on to the off spring. Cross linking provides more variation in the populations gene pole . Gametes are produced through this cell division process .There are 8 stages of meiosis: Prophase I, Metaphase I, Anaphase I, Telophase I, Prophase II, Metaphase II, Anaphase II, Telophase II.

Phase one is Prophase I, this is when Spindles start to form as DNA starts to condensate and chromosomes become visible as terards. Phase two is Metaphase I, where Tetrads begin to line up in the middle of the cell. And the spindles have now fully formed. During prophase I and metaphase I, genetic recombination occurs. Phase three, is Anaphase I in which Tetrads separate and two chromatids move toward opposite poles of the cell. Phase four, is Telophase I where the two chromatids decondense and nuclear membranes reforms around them. Cytokinesis then takes place forming two daughter cells, each nucleus is now haploid. Now…
