• B. It ensures offspring are genetically identical to the parent.
• C. It results in faster population growth compared to asexual reproduction.
• D. It allows for genetic diversity among offspring.

Answer: (D)

Verified step by step guidance

1. Understand the concept of sexual reproduction: Sexual reproduction involves the combination of genetic material from two parents, resulting in offspring with genetic variation.
2. Compare with asexual reproduction: Asexual reproduction involves a single organism reproducing without the fusion of gametes, leading to offspring that are genetically identical to the parent.
3. Identify the role of genetic diversity: Genetic diversity is crucial for the survival and adaptation of species, as it allows populations to adapt to changing environments and resist diseases.
4. Evaluate the advantages of genetic diversity: Genetic diversity increases the chances of some individuals in a population surviving environmental changes, thus contributing to the long-term survival of the species.
5. Conclude the main advantage: The main advantage of sexual reproduction is that it promotes genetic diversity among offspring, which is essential for the adaptability and evolution of species.
