Reproduction

• What are the two main types of reproduction?

  Asexual and sexual reproduction
• How many parents are involved in asexual reproduction?

  One parent
• What type of cell division occurs in asexual reproduction?

  Mitosis
• What is the result of asexual reproduction?

  Genetically identical offspring
• How many parents are involved in sexual reproduction?

  Two parents
• What types of cell division are involved in sexual reproduction?

  Meiosis and mitosis
• What is unique about the offspring produced in sexual reproduction?

  They contain a mixture of the parents' genes
• What does meiosis produce in terms of chromosome number?

  Cells with half the normal number of chromosomes
• How does the cell divide during meiosis?

  Each new cell has one copy of each chromosome
• How many gametes are produced after meiosis?

  Four gametes
• What is unique about the gametes produced by meiosis?

  They are genetically different
• Where are gametes formed?

  In the reproductive organs
• What are the male and female gametes in animals?

  Sperm and egg
• What are the male and female gametes in plants?

  Pollen and ovule
• What happens during fertilization?

  The normal number of chromosomes is restored
• What occurs after the fertilized cell divides?

  It forms an embryo
• What are the key differences between asexual and sexual reproduction?

  • Asexual: One parent, mitosis, identical offspring
  • Sexual: Two parents, meiosis and mitosis, mixed genes
• What is the process of meiosis leading to gamete formation?

  1. Meiosis produces cells with half chromosomes
  2. Each cell divides to form four gametes
  3. Gametes are genetically different
• What is the role of fertilization in reproduction?

  • Restores normal chromosome number
  • Leads to the formation of an embryo
