The figure shows zygotine stage of prophase-I of meiosis-I . During this stage, bivalent chromosomes clearly appear as tetrads. Pachytene stage is characterized by the appearance of recombination nodules, the sites at which crossing over (exchange of genetic material) occurs between non-sister chromatids of the homologous chromosomes.
