Sex Cells

Mitosis replicates a cell with a complete set of 46 chromosomes into daughter cells that are each Identical to each other. Mitosis is when a cell splits to two. Meiosis is just like mitosis except twice. Girls and boys both have sperm cells. You need cells to reproduce. There are very good reasons why you can't split into to two like your cells because your clone will look like half your dad and mom. We all come from one single cell. Chromosomes can trade DNA. All eggs produced by the same woman have a slightly different genetic code; the same for sperm and men. Meiosis is a cell that allows you to do sexual reproduction. Only eukaryotic cells can use Mitosis. Brothers and sisters sometimes look like each other or not look like each other, but they have the same mom and dad. Kids have their mother's cells. Boys have xy chromosomes and girls have xx chromosomes every person has x chromosomes but only boys have y chromosomes. Egg cells are the biggest cells. If the sperm is a x you're a girl, if the sperm is a y you're a boy. Sex cells are not the same All of your body cells contain the same mix of DNA 46 chromosomes grouped into 23 pairs one in each pair is from your mom the other is from your dad. The pairs of chromosomes are very similar but not identical they contain versions of the same genes, or alleles in any spot for any given trait since they're so similar their called Homologous chromosome pairs mean the same. Meiosis was discovered in sea urchin eggs in 1876 by a German biologist called Oscar Hertwig It was described again in 1883. Mitosis and  was observed first by Walther Flemming. Mitosis has lots of stages, like: Interphase, Preprophase, Prophase, Prometaphase, Metaphase, Anaphase, Telophase and Cytokinesis. You cannot look like your mom or your dad, but you can look like your brother or sister. Just like Mitosis theirs a spell between rounds of cell definition where the cells are gearing up for the next big split, and this is called interface when all the key players are replicating them selves the long strings of DNA in the Nucleus begin to duplicate leaving two copies of every strand. Meiosis II, Process ends with Telophase II. Polar bodies are useless, Polar bodies are not useless for plants. Mitosis and Meiosis are very similar. When chromosomes are attached, they are called the chromatid. Life would be more less stress full if you had a clone. You need sperm cells to reproduce. The sperm shares genetic information with the egg. Chromosomes share genetic information. You have a billion cells. All of our sex cells are not the same.
