A process that is carried out at the cellular level that results in the assembly, arrangement of constituent parts, or disassembly of chromosomes, structures composed of a very long molecule of DNA and associated proteins that carries hereditary information. The process by which sister chromatids are organized and then physically separated and apportioned to two or more sets. The alignment of chromosomes at the metaphase plate, a plane halfway between the poles of the meiotic spindle, during meiosis II. 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. 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. 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. 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. 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. The cell cycle process whereby sister chromatids are organized and then physically separated and randomly apportioned to two sets during the second division of the meiotic cell cycle. 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 cell cycle process whereby the centromeres of sister chromatids are physically detached from each other during meiosis. The process by which spindle microtubules become physically associated with the proteins making up the kinetochore complex during meiosis II. During meiosis II sister kinetochores are situated facing opposite spindle poles and bipolar attachment of the sister chromosomes to the spindle occurs. The directed movement of sister chromosomes from the center of the spindle towards the spindle poles, mediated by the shortening of microtubules attached to the chromosomes, during meiosis II.
