Question:
What is the advantage of cloning an adult animal rather than an embryo?
▶️Answer/Explanation
Ans: The traits of the adult are known; adults with the most desirable traits can be selected for cloning.
Question:
Is the natural process of human embryos splitting to produce identical twins a form of cloning?
▶️Answer/Explanation
Ans: Biologically/genetically it is no different from other natural methods of cloning; but identical twins are unlikely to welcome being regarded as clones.
Question:
What are the ethical objections to cloning humans?
▶️Answer/Explanation
Ans: Individuals resulting from adult cloning have a high risk of health problems/shortened life expectancy; cloning humans is unnatural/is ‘playing God’; only wealthy individuals are likely to be able to afford it; the Earth is overpopulated so each person should only be allowed to live once and not be given another life through cloning; obtaining embryonic stem cells requires the destruction of embryos that can then not be used for IVF.
