![]() Few fundamental things that you should know The haploid cells are the gametes which, in men and women, correspond respectively to spermatozoa and oocytes, which, thanks to fertilization, will join their chromosomal set. So that a total of 4 haploid cells will be formed, that is, with halved chromosomal equipment. After the exchange, the chromosomes separate, giving life to two daughter cells that will undergo a second division. In other words, they exchange portions of DNA. In the first meiotic phase, the chromosomes are duplicated to form pairs of homologous chromosomes that undergo the crossing over process instead of immediately separating. The phases of Meiosis are identical to mitosis but repeated twice. Meiosis is instead defined as a process of sexual reproduction because it takes place in the reproductive organs. The result will be the formation of two cells containing the same genetic information. ![]() In the final phase of mitosis, the sister chromatids will separate, migrate in opposite directions, and be enclosed within the new nuclei. To achieve this, the first phase of mitosis involves the duplication of the cell nucleus and the simultaneous reproduction of chromosomes, and therefore of the DNA, which will give rise to pairs of sister chromatids. Getting Know: What is the differences between mitosis and Meiosis? ![]()
