Meiosis reduces the number of chromosomes carried by a diploid organism by half, partitioning precisely one haploid genome into each gamete. The basic events of meiosis reflect three meiosis-specific processes: first, pairing and synapsis of homologous chromosomes; second, high-frequency, precisely controlled, reciprocal crossover; third, the regulation of sister-chromatid cohesion (SCC), such that during anaphase I, SCC is released along the chromosome arms, but not at the centromeres.
