  • Cloning has both potential benefits and risks in agriculture and medicine.
  • Benefits and risks of cloning overlap with those of selective breeding and asexual reproduction.
  • Cloning produces offspring with known characteristics quickly, faster than selective breeding.
  • Cloning can be used to preserve endangered species by enabling reproduction when few individuals remain.
  • A risk of cloning is the reduction of the gene pool, increasing susceptibility to widespread disease damage.
  • Cloned organisms (CLOs) may not be as healthy as the original, exemplified by Dolly the sheep who died younger than her donor.
  • Benefits of cloning include quick reproduction of desired traits and preservation of endangered species.
  • Risks include reduced genetic diversity leading to disease vulnerability and potentially poorer health of clones.
  • Students are advised to familiarize themselves with the benefits and risks of cloning for exam preparation.
