Normal babies are made from the joining of genes from sperm and egg. There is evidence that in clones this imprinting does not work properly. There is no way to screen any embryo to detect this problem. We know very little about the long-term health of clones. There is some evidence that they may not live as long as conventional humans and may have health problems.
Studies are ongoing.
It would not be a complete copy because there are some important genes that would be contributed by the egg donor. These genes reside outside the nucleus. This could result in a changed appearance and personality. If the recent research on the human genome has taught us anything, it is that we are far more than just our genes. In most countries that carry out advanced biomedical research it is.
