Genetic Variation in Sexual Reproduction

Steps:

• Recall that sexual reproduction involves fusion of gametes from two parents, combining genetic material.
• Compare to asexual reproduction, which produces clones with identical genetics.
• Identify advantages: sexual reproduction creates offspring with unique gene combinations.
• Evaluate choices: only B matches the benefit of diversity for adaptation.

Why B is correct:

• Sexual reproduction shuffles genes through meiosis and fertilization, producing genetically varied offspring that enhances species survival via natural selection.

Why the others are wrong:

• A: Asexual reproduction is faster as it skips gamete formation and fertilization.
• C: Sexual reproduction requires two parents, unlike asexual which needs one.
• D: Many plants rely on pollinators for sexual reproduction to transfer pollen.

Final answer: B
