Cloning is the process of replication of organism in order to reproduce
             favorable or remove undesirable traits from the product (clone). In last
             half century, there has been rapid advancement in scientific technology,
             which has resulted in discoveries such as of DNA structure, the stem cell,
             and with production of cloned sheep Dolly, curiosity and ethical issues
             have elevated concerning human cloning.
             There are several benefits and dangers of cloning of human genes. With
             advances in discovery of stem cell, the process of transplantation would be
             With the storage of stem cells the waiting time to find an organ for
             transplant and chances of rejection by patient would be decreased.
             Secondly, because the stem cells can mutilate0 on they're own, diseased or
             faulty tissues in rare diseases can be replaced e.g. the implantation of
             fetal stem cells in patients suffering from Parkinson's disease. Thirdly
             stem cells can help in the drug development. Instead of testing drugs in
             initial stages of development on human, they will experimented with cells
             until proven safe for human. Fourthly it can allow fertilization for
             However, there are many adverse physical and psychological effects, as well
             as ethical issues relating to human cloning or therapeutic cloning. By
             altering physical traits, the danger of creating a super human or subhuman
             clones is possible .As the clones will be produced from adult somatic
             cells, there is possibility any defect or mutation already present in cell
             will manifest itself in the clone. Further, lack of knowledge of effects of
             any alteration in an individual on future generation adds to threats or
             The couples that will opt for cloning will be affected psychologically.
             First, because the child will be replica of one parent second, the child
             being identical to one of parent will have problems of identity and self-
