Why might it be beneficial for sea stars to be able to reproduce both sexually and asexually?

• A. It allows for genetic diversity and rapid population growth.
• B. It limits the number of offspring produced each season.
• C. It ensures that all offspring are genetically identical.
• D. It prevents the spread of diseases within the population.

Answer: (A)

Verified step by step guidance

1. Understand the two modes of reproduction: Sexual reproduction involves the combination of genetic material from two parents, leading to genetic diversity among offspring. Asexual reproduction involves a single organism reproducing without the genetic input of another, resulting in offspring that are genetically identical to the parent.
2. Consider the benefits of genetic diversity: Sexual reproduction allows for genetic variation, which can be beneficial for adapting to changing environments and resisting diseases.
3. Consider the benefits of rapid population growth: Asexual reproduction allows for quick population increase since it does not require a mate and can produce many offspring in a short period.
4. Evaluate the options: The ability to reproduce both sexually and asexually provides sea stars with the flexibility to adapt to different environmental conditions and challenges.
5. Conclude that the combination of genetic diversity from sexual reproduction and rapid population growth from asexual reproduction is advantageous for sea stars, allowing them to thrive in various environments.
