Meiosis Definition Stages Purpose With Diagram Learn about meiosis, the process of cell division that reduces the number of chromosomes in sexually reproducing animals. find out the phases, functions and examples of meiosis i and meiosis ii. Learn how meiosis produces haploid gametes from a diploid cell by dividing twice. see the stages of meiosis i and ii, the functions of meiosis, and the differences between meiosis and mitosis.
Mitosis And Meiosis Stages There are two stages or phases of meiosis: meiosis i and meiosis ii. before a dividing cell enters meiosis, it undergoes a period of growth called interphase. at the end of the meiotic process, four daughter cells are produced. g1 phase: the period prior to the synthesis of dna. The process of meiosis is characteristic of organisms that reproduce sexually. such species have in the nucleus of each cell a diploid (double) set of chromosomes, consisting of two haploid sets (one inherited from each parent). these haploid sets are homologous—i.e., they contain the same kinds of genes, but not necessarily in the same form. This is an accepted version of this page this is the latest accepted revision, reviewed on 22 august 2024. cell division producing haploid gametes for the figure of speech, see meiosis (figure of speech). for the process whereby cell nuclei divide to produce two copies of themselves, see mitosis. for excessive constriction of the pupils, see miosis. for the parasitic infestation, see myiasis. Meiosis stages diagram. meiosis involves two successive stages or phases of cell division, meiosis i and meiosis ii. each stage includes a period of nuclear division or karyokinesis and a cytoplasmic division or cytokinesis. although not a part of meiosis, the cells before entering meiosis i undergo a compulsory growth period called interphase.

Meiosis ii. prophase ii and prometaphase ii. these stages are identical to their counterparts in meiosis i. metaphase ii. in metaphase ii, chromosomes line up in single file along the equator of the cell. this is in contrast to metaphase i, where chromosomes line up in homologous pairs. fig 6 – image of metaphase ii.
