The propagation of most sexually reproducing species is possible due to a specialized form of cell division known as meiosis, which leads to the formation of haploid gametes that fuse upon fertilization, reconstituting the species ploidy. A hallmark of meiosis is the ability to segregate homologous chromosomes away from each other, thereby reducing the chromosome set by half. Mechanistically, this involves pairing, synapsis, and the reciprocal exchange of genetic material (crossover recombination) between homologous chromosomes during prophase I. These events ensure that homologs remain physically connected even after they desynapse, allowing for their proper alignment at the metaphase plate and
