Asexual and Sexual Reproduction

• How many pairs of chromosomes do human cells contain?

  23 pairs of chromosomes
• What type of cell division do human cells undergo to produce identical cells?

  Mitosis
• What are gametes in humans?

  Sperm cells and egg cells
• How many chromosomes do human gametes contain?

  23 single chromosomes
• What type of cell division produces gametes?

  Meiosis
• How do gametes differ from somatic cells?

  Gametes have single chromosomes
• What is a key difference between meiosis and mitosis?

  Meiosis produces non-identical cells
• What is the result of meiosis in flowering plants?

  Pollen and egg cells
• What is fertilization in sexual reproduction?

  Fusion of male and female gametes
• What does sexual reproduction lead to in offspring?

  Variation in genetic information
• What is a key characteristic of asexual reproduction?

  Only one parent involved
• What are the offspring of asexual reproduction called?

  Clones
• What type of cell division occurs in asexual reproduction?

  Mitosis
• What is the genetic relationship between offspring and parent in asexual reproduction?

  Offspring are genetically identical
• What are the main features of sexual reproduction?

  • Involves fusion of male and female gametes
  • Results in variation in offspring
  • Gametes are produced by meiosis
• What are the main features of asexual reproduction?

  • Involves only one parent
  • Offspring are clones of the parent
  • Gametes are not involved
  • Only involves mitosis

  • Animals
  • Flowering plants
• What types of organisms perform asexual reproduction?

  • Many plants
  • Some animals (e.g., aphids)
