Result of meiosis
The result obtained after division by meiosis is four cells (sometimes only one) with half the genetic information (n) of the parent cell. In addition, each daughter cell is different because the crossover homologous chromosome has allowed that genetic material and the resulting chromatids are all different exchanged.
Cells obtained in meiosis (n) can join other cells (gametes) and produce a new cell with a normal chromosome set (diploid, 2n).
The exchange of genetic material between different cells allows the offspring to be different from the parents. This genetic variability allows the possibility of adaptation of some organisms to the environment in which they live, being able to survive better those that are better adapted.
