genetic of a single individual. There are different methods to do with this type of cloning but the most common is somatic cell nuclear transfer. The first step is to remove the nucleus from the mother egg. Second is to take a somatic cell from the individual being cloned, take out the DNA and put it in the egg of the mother.
