At the chromosome level, several actions are required for the normal course of meiosis: pairing in the chromosomes, which turn into physically close to one particular an additional, synapsis, which results in the formation of a proteinaceous structure called the synaptonemal complex (SC), closely associating homologous chromosomes, along with the segregation of a single chromosome from each pair inside the two daughter cells [1]. All these steps are intimately linked for the tightly regulated meiotic recombination course of action. Recombination is initiated by programmed double-strand breaks (DSB). Numerous models for DSB repair have already been proposed, leading to crossover (CO) and non-crossover (NCO) events at the end of pachytene [2]. NCO are thought to outnumber CO by a issue of ten in mice and humans [1], but what orientates the repair mechanisms towards CO or NCO events, and at what stage, remains elusive. Numerous regulatory mechanisms, operating at unique levels, have evolved to make sure a right variety of CO per cell. Homeostasis allows a minimum number of CO to become maintained when the number of DSB is lowered [3]. Other mechanisms, source of the "obligatory CO" rule, make sure that at the least 1 CO per chromosome is formed, independently of its size [4]. Lastly, a extended identified phenomenon referred to as "crossover interference" affects the distances among CO along the distinct chromosomes by discouraging CO formation within the vicinity of other individuals [5]. Interference assumes the existence of some form of communication along the chromosomes. The mechanisms involved in that communication are not nicely understood, but some authors have reported that interference can act more than long distances, and is propagated through the centromeres [6]. The location of CO events is also effectively regulated. For example, some regions are extra prone to CO (distal ends of acrocentric or metacentric chromosomes) than others (pericentromeric regions of metacentric chromosomes) [7,8]. Additionally, quick genomic regions of about 1? kb, title= rstb.2013.0181 known as "recombination hotspots", are mainly involved in recombination events [9]. In some species, like mouse and Man, a particular, quickly evolving gene (Prdm9), has been shown to possess a significant role in specifying recombination hotspots [1]. As illustrated within the previous paragraphs, and thanks to enormous analysis efforts, our know-how on the (molecular) biology of meiosis has considerably improved more than the years. Nevertheless, as stated by Mercier et al.
