Meiosis is type of cell division where the haploid daughter cells contain half of the genetic component of the parent diploid cell. This type of cell division occurs on the reproductive cells of organism. Meiosis is divided into two parts, the meiosis I and meiosis II. At Meiosis I, there is a similar pattern of cell division as to the mitosis which leads to producing two diploid nuclei with two pairs of chromosomes. As it enters the Meiosis II, the copying of chromosome is stopped. Instead, the chromosomes are halved to give way to production of haploid daughter cells.
If the chromosomes number is 24, the end product would have a chromosomes number of 24 at the end of telophase I but will be halved to 12 at the end of telophase II.
