- This checks the loss of water through transpiration and provides the carbon dioxide for photosynthesis.
Answer: Fewer harmful mutations are inherited by sexual reproduction than by asexual reproduction.
Explanation:
A germline mutation is the mutation in the germ cells (of the fully developed sperm and ovum) of the parents. When the affected parents undergoes with the sexual reproduction the mutations are passed from the parents to the offsprings. When either the mutated oocyte or mutated sperm meet to form a zygote the precursor of new life. Thus few mutations are inherited by sexual reproduction than by asexual reproduction.
