  • achytene is the third phase of meiosis 1. In pachytene, the exchange of the DNA segments takes place between non-sister chromatids of homologous chromosomes.
  • This process is called crossing over and it leads to recombination.
  • Chiasma is a region where two homologous chromosomes undergo crossover.
    Thus the correct answer is option C.
