How is sexual reproduction different from asexual reproduction?

• A. Sexual reproduction occurs without the involvement of gametes.
• B. Sexual reproduction involves the fusion of gametes from two parents, resulting in genetic variation.
• C. Sexual reproduction results in offspring that are clones of the parent.
• D. Sexual reproduction produces offspring that are genetically identical to the parent.

Answer: (B)

Verified step by step guidance

1. Understand the basic definitions: Sexual reproduction involves two parents and the fusion of their gametes (sperm and egg), while asexual reproduction involves only one parent and does not involve gametes.
2. Recognize that sexual reproduction leads to genetic variation because the offspring inherit a combination of genes from both parents, resulting in unique genetic combinations.
3. Identify that asexual reproduction results in offspring that are genetically identical to the parent, often referred to as clones, because there is no exchange or mixing of genetic material.
4. Consider the role of gametes: In sexual reproduction, gametes (sperm and egg) are crucial as they carry half of the genetic information from each parent, which combines to form a new organism.
5. Conclude that the key difference is that sexual reproduction involves genetic diversity due to the fusion of gametes from two parents, whereas asexual reproduction does not involve gametes and results in genetically identical offspring.
