1. Meiosis is the process that creates sperm and egg cells.
  2. Sperm and egg cells have only half the genetic information of a normal cell, they are haploid.
  3. First the chromosomes replicate as usual.
  4. Then matched pairs align themselves at their centromeres, some dna may be passed between matched pairs (crossover).
  5. The cell divides.
  6. Finally the two daughter cells divide again, leaving one half complement of DNA in each of 4 cells.
