Mechanisms of Cell Reproduction

Mitosis: Process of cell duplication in which each new cell receives an exact copy of the original 46 chromosomes.

Meiosis: Process of cell division through which sex cells (sperm and ovum) or "gametes" are created.

  1. Gametes have 23 chromosomes
  2. The 23 chromosomes are unique
  3. Uniqueness due to gene exchanges (crossing over)
