Answer:
Meiosis, on the other hand, is only used with one purpose in the human body: the production of gametes or sex cells, that is, sperm and ovules. Its objective is to make daughter cells with exactly half of chromosomes than the initial cell.
By definition, meiosis in humans is a process of cell division that takes us from a diploid cell, one with two sets of chromosomes, to haploid cells, which have only one set of chromosomes.
During prophase I, differences with mitosis begin to appear. As in mitosis, chromosomes begin to condense, but in meiosis I, they also form pairs. Each chromosome is carefully aligned with its homologous partner so that the two pair up in positions corresponding to their entire length.
For example, in the following image, the letters A, B and C represent genes found at particular points on the chromosome, with upper and lower case letters for the different shapes, or alleles, of each gene. The DNA is broken in the same place at each homologue, in this case between the B and C genes, and reconnected in a crosslinked pattern so that the homologs exchange part of their DNA.
Cells move from meiosis I to meiosis II without copying their DNA. Meiosis II is a shorter and simpler process than meiosis I, and you might find it helpful to think of meiosis II as "mitosis for haploid cells."
The cells that enter meiosis II are those created in meiosis I. These cells are haploid, have one chromosome of each homologous pair, but their chromosomes are still formed by two sister chromatids. In meiosis II, sister chromatids separate and produce four haploid cells with non-duplicated chromosomes.
