What are the differences between mitosis and meiosis?

Mitosis and meiosis are cell division processes by which one cell is divided into daughter cells. Specifically, the concepts apply to the phases of the division of cells in which cell chromosomes that contain copies of the genetic information of the organism are divided. Mitosis and meiosis differ in different ways, including the number of daughter cells, and the number of copies of genetic information contained in each daughter cell. For example, in mitosis, the parent cell is divided and consists of two daughter cells that contain two copies of each of the chromosomes of the superior cells. On the other hand, one parent cell is divided twice in meiosis and forms four daughter cells that contain only one copy of each chromosome.

These differences in mitosis and meiosis results are directly associated with the functions of two forms of cell division. Mitosis, which is divided into two identical cells, is simply used for growth, development and repair. One skin, for example, the cell is divided to form two identical skin cells. On the other side of meiosis produces gamets such as eggs and sperm in animals or spores in mushrooms. One -time chromosomal copy in each of the cells of meiotic daughters contains a combination of paternal and maternal genetic information, which ensures that offspring will not be genetically identical to any parent.

steps that occur during meiosis and mitosis processes also differ somewhat. The differences occur primarily because there are two divisions during meiosis, while only one occurs during meiosis, although there are other differences. It is important to realize that daughter cells resulting from mitosis are identical genetic matches with the parent cell, while cells that are the result of meiosis are not. The genetic integrity of the body depends on the consistent division of cells that do not change the genetic code. However, the patrons are often better equipped for survival if they receive a combination of properties that is not a genetic replica of one of the parents.

One main difference between mitosis and meiosis, which can significantly contribute to genetic diversity in descendants, is referred to as "crossing" or "chromosomal crossover". The crossing occurs only in meiosis. Homologous chromosomes can physically "replace" the chromosomal segments, ensuring that the information contained in the only chromosome in the meiosis daughter cell is genetically different from the information contained in the genome of the superior organism.
