GO:0051304 chromosome separation The cell cycle process in which paired chromosomes are detached from each other. Chromosome separation begins with the release of cohesin complexes from chromosomes; in budding yeast, this includes the cleavage of cohesin complexes along the chromosome arms, followed by the separation of the centromeric regions. Chromosome separation also includes formation of chromatid axes mediated by condensins, and ends with untanglement of inter-sister catenation catalyzed by topoisomerase II (topo II). 2

GO:0007110 meiosis I cytokinesis A cell cycle process that results in the division of the cytoplasm of a cell after meiosis I, resulting in the separation of the original cell into two daughter cells. 1
GO:0040038 polar body extrusion after meiotic divisions The cell cycle process in which two small cells are generated, as byproducts destined to degenerate, as a result of the first and second meiotic divisions of a primary oocyte during its development to a mature ovum. One polar body is formed in the first division of meiosis and the other in the second division; at each division, the cytoplasm divides unequally, so that the polar body is of much smaller size than the developing oocyte. At the second division in which a polar body is formed, the polar body and the developing oocyte each contain a haploid set of chromosomes. 1
GO:0007136 meiotic prophase II Prophase occurring as part of meiosis II. Prophase is the part of nuclear division in which, canonically, chromosomes condense and the two daughter centrioles and their asters migrate toward the poles of the cell. Meiosis II is the second phase of meiosis, in which cells divide and separate the two chromatids in each chromosome. 1
GO:0051316 attachment of spindle microtubules to kinetochore involved in meiotic chromosome segregation The cell cycle process in which spindle microtubules become physically associated with the proteins making up the kinetochore complex contributing to meiotic chromosome segregation. 1
GO:0048236 plant-type spore development The process whose specific outcome is the progression of the spore over time, from its formation to the mature structure. The spore gives rise to gametophytes. 1
GO:0071930 negative regulation of transcription involved in G1/S phase of mitotic cell cycle Any process that stop, prevents or decreases transcription as part of the G1/S transition of the mitotic cell cycle. 1

GO:0033316 meiotic spindle assembly checkpoint A cell cycle checkpoint that delays the metaphase/anaphase transition of a meiotic cell cycle until the spindle is correctly assembled and chromosomes are attached to the spindle. 1
GO:0034088 maintenance of mitotic sister chromatid cohesion The process in which the association between sister chromatids of a replicated chromosome is maintained as chromosomes condense, attach to the spindle in a bipolar orientation, and congress to the metaphase plate during a mitotic cell cycle. 1

GO:0031566 actomyosin contractile ring maintenance The cell cycle process in which the contractile ring is maintained in response to the cytokinesis checkpoint; that is when cytokinesis is delayed awaiting completion of nuclear division or the correct formation of cytokinetic structures. This process occurs in the context of cytokinesis that takes place as part of a cell cycle. 1
