In meiosis recombination occurs:
WebIn reality, crossing-over between chromatids during prophase I of meiosis mixes up pieces of chromosomes between homologue pairs, a phenomenon called recombination. Because recombination occurs ... WebDuring the pachytene stage, bivalent chromosome now clearly appears as tetrads. This stage is characterized by the appearance of recombination nodules, the sites at which crossing over between non-sister chromatids of the homologous chromosome. And then crossing over takes place. So the correct answer is "Pachytene".
