Genetic improvement is the process of altering the genetic composition of an organism to produce appropriate qualities. Geneticists insert new and favorable genetic information to support or completely replace genetic information. Scientists have already used the method to create mice, which experienced rapid muscle growth after the process, and although implementing this technology on humans is a much more complicated task, the possibility becomes closer to reality with each new technology and discovery introduced. Eventually, parents may be able to choose the child's hair color, skin tone, eye color, and even personality. They may also be able to choose how smart their child should be. Cloning Clones are organisms or species that are exact genetic duplicates. Every single fragment of their DNA is identical and the same. Clones can also happen naturally, for example identical twins are one of the examples of cloning. Now they can also be made in the laboratory using the latest technology. There are two possible ways to create an exact genetic copy of an organism in a laboratory: somatic cell nuclear transfer and artificial embryo twinning.1. Artificial embryo
