LS1.7: Asexual vs. Sexual Reproduction

California blackworms, also known as mudworms, are able to break apart. Each body section that broke apart is able to become an identical new worm. What type of reproduction does this example represent?

• Sexual reproduction

• Asexual reproduction

What are some of the facts about asexual reproduction?

• Takes only one mate to reproduce and takes a longer time to reproduce
• Takes a shorter amount of time to reproduce and it takes two mates to reproduce
• Reproduces diverse offspring and takes a longer time to reproduce
• Takes only one mate to reproduce and takes a shorter time to reproduce

If an environment suddenly changes, which type of reproduction would be most beneficial? Why?

• Asexual, because asexual organisms always have variation within species.
• Sexual, because sexual organisms have variation within species.
• Both Asexual and Sexual reproduction would be beneficial, because they both have variation within species.
• Asexual, because asexual organisms have no variation, so they can adapt to a changing environment.

Which statement best describes the process of asexual reproduction?

Amoeba reproduce asexually? Which of the following statements best describes the new amoeba cell?

• The new amoeba cell only contains half of the genetic material from the parent amoeba cell.

• The new amoeba cell is a different species than the parent amoeba cell

What is true about the offspring in this image?

• They will be genetically unique and not identical to their parents

• They will share the identical DNA as their parent
