A key event that occurs in Prophase I of meiosis but not in prophase of mitosis is:

  • A: Chromosome duplication.
  • B: Synapsis of homologous chromosomes.
  • C: Alignment of chromosomes at the metaphase plate.
  • D: Separation of sister chromatids.

Explanation

The summary table explicitly states that 'Synapsis of homologous chromosomes' occurs during Prophase I of meiosis and 'Does not occur' in mitosis. This pairing and subsequent crossing over is a hallmark of meiosis.
