Progression through the phases of the meiotic cell cycle, in which canonically a cell replicates to produce four offspring with half the chromosomal content of the progenitor cell. The formation of the spindle midzone, the area in the center of the spindle where the spindle microtubules from opposite poles overlap, as a part of the process of meiosis. A cell cycle process comprising the steps by which a cell progresses through M phase, the part of the meiotic cell cycle during which meiosis takes place. A cellular process that is involved in the progression of biochemical and morphological phases and events that occur in a cell during successive cell replication or nuclear replication events. The cell cycle process whereby oscillatory movement of the nucleus during meiotic prophase I occurs. This oscillatory movement is led by an astral microtubule array emanating from the spindle pole body, and driven by the microtubule motor cytoplasmic dynein. It is known to play a central role in meiotic recombination and homologous chromosome pairing; as observed in S. pombe. A cell cycle process comprising the steps by which a cell progresses through one of the biochemical and morphological phases and events that occur during successive cell replication or nuclear replication events. Any process that modulates the frequency, rate or extent of meiosis, the process by which the nucleus of a diploid cell divides twice forming four haploid cells, one or more of which usually function as gametes. The cell cycle process whereby the dynamic reorganization of telomeres occurs in early meiotic prophase, during which meiotic chromosome ends are gathered in a bouquet arrangement at the inner surface of the nuclear envelope proximal to the spindle pole body. This plays an important role in homologous chromosome pairing and therefore progression through meiosis. A cell cycle process comprising the steps by which a cell progresses through the first phase of meiosis, in which cells divide and homologous chromosomes are paired and segregated from each other, producing two daughter cells. Any process that activates or increases the frequency, rate or extent of meiosis. A cell cycle process comprising the steps by which a cell progresses through the nuclear division phase of a meiotic cell cycle, the specialized nuclear and cell division in which a single diploid cell undergoes two nuclear divisions following a single round of DNA replication in order to produce four daughter cells that contain half the number of chromosomes as the diploid cell. Meiotic division occurs during the formation of gametes from diploid organisms and at the beginning of haplophase in those organisms that alternate between diploid and haploid generations. A cell cycle process comprising the steps by which a cell progresses through the second phase of meiosis, in which cells divide and separate the two chromatids in each chromosome. The process by which genetic material, in the form of chromosomes, is organized into specific structures and then physically separated and apportioned to two or more sets during M phase of the meiotic cell cycle. The aggregation, arrangement and bonding together of a set of components to form the spindle that contributes to the process of meiosis. A process of chromosome organization that is involved in meiosis. A cell cycle process comprising the steps by which a cell progresses through the nuclear division phase of a meiotic cell cycle in the female germline. Any process that stops, prevents or reduces the frequency, rate or extent of meiosis. A cell cycle process comprising the steps by which a cell progresses through the nuclear division phase of a meiotic cell cycle in the male germline. A cell cycle process comprising the steps by which a cell progresses through M phase, the part of the cell cycle comprising nuclear division.
