Introduction Meiosis consists of a single round of DNA replication and two consecutive rounds of cell division, halving genome ploidy and producing genetically diverse gametes (Villeneuve & Hillers, 2001). During meiosis, homologous chromosomes undergo programmed DNA double-strand breaks (DSBs), pairing, synapsis, and homology-directed repair, resulting in crossovers or noncrossovers (Hunter, 2015; Zickler & Kleckner, 2023).

AbstractMeiotic crossovers rearrange existing genetic variation between homologous chromosomes, profoundly affecting genomic diversity. Crossovers are typically constrained to 1-3 events per chromosome pair, and their distribution is shaped by chromatin accessibility and DNA polymorphisms. Genome-wide crossover maps can be generated in plants by high-throughput short-read sequencing or linked-read sequencing.
