  1. Which type of cell division produces non-identical cells?

    Show answer

    Meiosis.

  2. Which type of cell division produces genetically identical cells?

    Show answer

    Mitosis.

  3. What is sexual reproduction?

    Show answer

    Reproduction involving the joining (fusion) of male and female gametes.

  4. What are the male and female gametes in animals?

    Show answer

    Sperm (male) and egg cells (female).

  5. What are the male and female gametes in flowering plants?

    Show answer

    Pollen (male) and egg cells (female).

  6. Why does sexual reproduction lead to variety in the offspring?

    Show answer

    Because genetic information from two parents is mixed when the gametes fuse.

  7. The formation of gametes involves ?.

    Show answer

    meiosis

  8. How many parents are involved in asexual reproduction?

    Show answer

    Only one parent, with no fusion of gametes.

  9. Why are the offspring of asexual reproduction genetically identical?

    Show answer

    There is only one parent and no fusion of gametes, so there is no mixing of genetic information.

  10. What term describes genetically identical offspring produced by asexual reproduction?

    Show answer

    Clones.

  11. The only type of cell division involved in asexual reproduction is ?.

    Show answer

    mitosis
