Reproduction

• Sexual reproduction


  • Type of reproduction
  • Involves the production of gametes by meiosis
  • A gamete from each parent fuses to form a zygote
  • Genetic information from each gamete is mixed so the resulting zygote is unique
• Gametes


  • Sex cells (sperm cells and egg cells in animals, pollen and egg cells in flowering plants)
  • Haploid (half the number of chromosomes)
• Meiosis


  1. Form of cell division involved in the formation of gametes (non-identical haploid cells) in reproductive organs

  2. Chromosome number is halved

  3. Involves two divisions
• Interphase


  Copies of genetic information are made during this process
