Genes are basically codes or instructions that inhibit or create in organisms cells. In recent years, scientists have learned how to manipulate parts of DNA by creating enzymes to remove or add certain genes. DNA is vastly complicated and organizations such as the Human Genome Project, which is trying to map all the genes in the human body, have helped people suffering from genetic diseases. Embryos that are produced for IVF treatment but not used can now legally be used for research into genetic diseases. In theory, a person could decide the exact appearance and nature of a child by manipulating genes in an embryo. Throughout history groups of people have been targeted as inferior or superior because they are born in a certain disposition perhaps supposedly seen as favorable in the eyes of God- genetic modification can change these aspects and would be no doubt advocated for by homicidal racist Adolph Hitler.
