Anaphase I

  • The homologous chromosomes of each bivalent separate from each other.
  • The separated homologous chromosomes move to opposite poles
  • Therefore, in this phase, the chromosomes separate and not the chromatids.
  • So, each chromosome will still have two sister chromatids.
  • Hence, anaphase I involve a reduction in the number of chromosomes.
