Mitosis and Meiosis

It is important that jail cells go finished mitosis because it makes individually new cell contain the same gentic information. If meiosis did not occur the reproduction would cease to exist. Mitosis is the process of chromosomes dividing. There atomic number 18 four steps that it goes through. Between cell social class the cells argon in interphase. During this there is cell growth and the genetic material such as DNA is contained in the chromosomes, duplicated so that when the cell divides each new cell has a full version of the same genetic material.First is prophase, which the chromosomes coil up and become visible. Second is metaphase, the chromosomes move in toward the center. Third is anaphase, and here is where the cromatids are pulled apart. Fourth and last, is the telophase, this is when a nuclear envelope forms around the chromosomes. If mitosis occurred in the gametes, when fertilization happens the offspring would receive a double dose of hereditary information. T o disallow this, it undergoes the reduction division of meiosis. Meiosis is a form of cell division that cuts the number of chromosomes in halves in the gametes.An organism would need to go through mitosis for growth, development, re checkmate and aintimate reproduction. Meiosis is important for eukayotic organisms, this causes production of gametes which is the organisms reproductive cells) for sexual reproduction. Mesoisi is very random in its way of separating homologus pairs. It randomly determins which of each pair ends up in each newly produced gametes. An organism with 23 pairs of chromosomes tin can produce 8,388,603 possible types of gametes. According to (2010), The process of meiosis also creates another(prenominal) opportunity to generate genetic diversity.During one phase of meiosis, called metaphase, the arrangement of each pair of homologous chromosomes is random, and different combinations of maternal and paternal chromosomes line up with varying orientations to cr eate new gene combinations on different chromosomes. This body process is called independent assortment. (para. Five).Reference (2010). Understanding Genetics growth and Reproduction.
