Why is sexual reproduction considered more efficient than asexual in generating variation?
AIt is faster than asexual reproduction (option)
BIt produces more offspring per parent
CIt combines DNA variations from two parents into novel offspring genomes
DIt does not need any DNA copying
Answer & Solution
Correct answer: C. It combines DNA variations from two parents into novel offspring genomes
1. Asexual variation comes only from copying errors, which are slow to accumulate.
2. Sexual reproduction combines variations already present in two parental DNAs.
3. Each offspring inherits a novel combination of pre-existing variants, accelerating variation.
