Asexual Reproduction Produces Clones Steps:

• Define asexual reproduction as producing offspring from a single parent without gamete fusion.
• Note that this process copies the parent's DNA exactly, creating identical clones.
• Compare to sexual reproduction, which involves genetic mixing via fusion.
• Evaluate each option against this definition to identify the matching statement.

Why A is correct:

• Asexual reproduction lacks genetic recombination, so offspring inherit identical DNA from the parent, per the principle of mitotic cell division.

Why the others are wrong:

• B: Many organisms, like bacteria and some plants, reproduce asexually as their primary method, not just in extremes.
• C: Fusion of diploid nuclei describes fertilization in sexual reproduction, not asexual.
• D: Environmental factors influence growth, so genetically identical offspring may vary in height.

Final answer: A
