Question

which argument supports the claim that sexual reproduction affects the genes of the offspring?
a sexual reproduction prevents the chromosomes from separating, allowing the complete set of each parents genes to be passed on to the offspring
b sexual reproduction combines genes from both of the parents, ensuring that the offspring is genetically different from the parents.
c. sexual reproduction utilizes the chromosomes from one parent, ensuring that the offspring is an exact copy of the parent.
d. sexual reproduction ensures the strongest, fittest genes from each parent are inherited by the offspring.

Explanation:

• Option A: In sexual reproduction, chromosomes do separate during meiosis. So this option is incorrect.
• Option B: Sexual reproduction involves the combination of genetic material (genes) from two parents (sperm and egg). This combination leads to genetic variation in the offspring, making them genetically different from the parents. This supports the claim that sexual reproduction affects the genes of the offspring.
• Option C: Sexual reproduction uses chromosomes from two parents (not one). Asexual reproduction (like binary fission in some organisms) can produce offspring that are exact copies (clones) of the parent. So this option is wrong.
• Option D: There is no mechanism in sexual reproduction that specifically ensures only the "strongest, fittest" genes are inherited. Genetic inheritance in sexual reproduction is more about the random combination of genes from two parents. So this option is incorrect.

Answer:

B. Sexual reproduction combines genes from both of the parents, ensuring that the offspring is genetically different from the parents.
