This event occurs in anaphase of mitosis and anaphase II of meiosis. The process of meiosis is divided into 2 stages. Four haploid daughter cells are produced at the end, unlike two diploid daughter cells in mitosis. Cite this Article Format. As an example, consider the meiosis II diagram above, which shows the end products of meiosis for a simple cell with a diploid number of 2n = 4 chromosomes. This process results in genetic variation and the 4 daughter cells formed at the end of meiosis are genetically dissimilar. 19 Which of the following occurs during meiosis? The second part of the meiosis, meiosis II, resembles mitosis more than meiosis I. Chromosomal numbers, which have already been reduced to haploid n) by the end of meiosis I, remain unchanged after this division. One difference is that Meiosis 1 starts with a diploid cell and Meiosis 2 starts with 2 haploid cells, each with a homologous pair. Answer (1 of 9): Meiosis is the division of cells to make gametes. Generally Diploid cells undergoes Meiosis cells division and due to this Haploid cells are formed at the end. Humans have 23 .

Separation of _____ occurs in anaphase II of meiosis. In meiosis, however, you start with a diploid cell that divides twice to produce four haploid cells. This results in two diploid cells that contain the same amount of DNA as the original parent cell. Your Citation . Select Exception. Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. The gametes produced in meiosis aren't genetically identical to the starting cell, and they also aren't identical to one another. Therefore, each cell has half the number of sister chromatids to separate out as a diploid cell undergoing mitosis. mla apa chicago. That is, they are haploid. Diploid (2 n) organisms rely on meiosis to produce meiocytes, which have half the ploidy of the parents, for sexual reproduction. Meiosis 1: Chromosomal cross-over occurs during prophase 1, by exchanging the genetic material between non-sister chromatids. The process in males and females also differ especially in terms of the actual gamete produced. During meiosis II, the sister chromatids within the two daughter cells separate, forming four new haploid gametes. 8.
