  • Meiosis alternates with mitosis from one to the next generation
  • Meiosis is essential for sexual reproduction
  • Passing of the same genetic system from one to next generation
  • Genetic recombination is possible from one to next generation

  • 2. 
    One of these events does not take place during meiosis
