sexual vs asexual repdoduction

• Chromosomes


  Genetic material in the nucleus of a cell
• Human cells

  • Contain 23 pairs of chromosomes in the nucleus
• Mitosis


  One cell is copied into two identical cells
• Gametes

  Cells where the chromosomes are not paired
• Human gametes

  • Sperm cells and egg cells
  • Contain 23 single chromosomes
• Meiosis

  • The type of cell division that produces gametes
  • Produces non-identical cells
• Meiosis takes place in flowering plants to produce pollen and egg cells
• Sexual reproduction

  • Involves the fusion of male and female gametes (fertilization)
  • Mixing of genetic information from both parents
  • Leads to variation in offspring
• Sexual reproduction

  • Puppies
• Asexual reproduction

  • Involves only one parent
  • Does not involve gametes
  • Offspring are genetically identical (clones)
  • Only involves mitosis
• Asexual reproduction


  • Aphids
  • Plants forming tiny buds
