breakage and reunion
breakage and reunion In genetics, the established model of crossing-over by the physical breakage and crosswise reunion of broken chromatids during the pairing of homologous chromosomes at the prophase I stage of meiosis. The points at which chromosomes cross over are termed chiasmata. The result of crossing-over is the mutual exchange between chromatids of parts which contain corresponding loci.
