1. What is done? Mention two advantages and two disadvantages of clones.
Answers
Answer:
Scientists around the world continue to argue the advantages of cloning in hopes of being able to research it more thoroughly, but more than 30 countries have already issued bans on human reproductive cloning. However, the countries of China, Sweden, England, Israel and Singapore do allow cloning for reasons that have nothing to do with human reproduction.

Answer: ADVANTAGES
1. It has great contribution to organ replacement.
Genetic cloning allows scientists to take small amounts of cells from a certain organ and use them to generate and harvest new organs that are entirely functioning. Considering the huge number of people on organ donation waiting lists, this is extremely beneficial.
2. It helps infertile couples to bear children.
One big advantage of cloning is that it allows infertile couples to reproduce, and the child would be genetically modified to fit what the parents want to appeal to other people. During the process, somatic cells are acquired from the male’s sperm and are injected into the female’s egg for fertilization. By the time the embryo has developed, it is then implanted to a surrogate mother, who will carry it for 9 months until birth. This means cloning can potentially ease fertility problems. What’s more, the children produced will have the DNAs and qualities of both parents, instead of just one of them.
DISADVANTAGES
1. It comes with a degree of uncertainty as of yet.
There is still a lot of repercussions and effects of cloning that remain unknown to date. After all, it is a new world of science that is still continually being discovered, and there is no convincing way to tell what the mental, social and medical consequences may be endured due to it. Also, the research and testing that are needed before embarking on something as insane as cloning humans still does not exist. Considering the problems that already exist with animal cloning, we can safely presume that the procedure will be a very large obstacle to begin with.
2. It decreases gene diversity.
The ability of humans to live greatly relies on the diversity of genes, which comes from parents who have different sets of genes. One big disadvantage of identical genes is that they will weaken our adaptations and power, which can make us subjected to certain diseases easily. Moreover, we should remember that the beauty of humanity lies in the differences among individuals, and cloning ruins this. Not to mention that it would eliminate surprise and predict expectancy.
