Asexual reproduction for infertile or gender-identical pairs
1. If the donator of the clone's genome lives near the child:
The child is regularly confronted with a version of itself that is older, more developed and has a certain personality. The child might learn to handle this if the reasons are explained early
and clearly, but it might cause serious identity problems later. The child will know its later outlook and some personal characteristics it has not discovered in itself yet.
2. If the donator of the clone's genome also brings up the child:
The problem in I./1. is bigger, as when seeing its further-developed biological counterpart regularly the child is also able to watch its development. If the donator dies, this might cause
heavy psychical damage.
In addition, it may be more difficult for the child to find friends, because cloning will probably remain an expensive and not widely used technique and potential friends will be frightened by it.
3. If the clone is confronted with its donator long after its birth and does not know that it is a clone / what a clone is:
The child is suddenly confronted with an older version of itself it was never prepared for. This can cause very big psychical damage.
4. If the clone is confronted with its donator later and was told that it is a clone in its youth:
Probably the best way to bring up a cloned child. It is unlikely that it will suffer from social isolation or psychical damage.
5. If multiple clones of the same age live together (with or without the donator):
Probably the most dangerous way to bring up clones. 2 cloned children living without their donator may grow up like twins, but the social problems will rise with the number of clones.
Twins have always been some kind of "attraction" and are likely to have social problems especially in their early childhood. For one of the oldest laws of humanity does still count: Those that look "alien" are treated like aliens.
Much enlightenment about cloning is necessary before such clonings should be allowed.
The easiest way of getting children for gender-identical or infertile pairs. Collides with the idea of many parents to transport parts of themselves to their children (although it is doubtful that transporting biology is more important than transporting ideas, which is possible with adopted children, too). There are lots of poor children in the world who have to grow up without parents and adoption is therefore not only an ethical alternative to cloning but also an ethical alternative to natural reproduction.
2. In-Vitro Fertilization:
(Short explanation: The mature egg cells of a human female are fertilized with male sperm outside the body and then inserted into the uterus of the same or another human
female for normal gestation.)
A good alternative to cloning that works for many pairs, especially since eggs, sperm and even embryos can be frozen for later impantation.
