As scientists made great leaps forward in the field of Genetics in the 21st century, scientists sought the next step: the manipulation of genes to alter the embryo and human life itself. By building genes artificially, scientists and parents could ensure that children had the best possible attributes for life. Based on these experiments, scientists were able to come out with brands of children. The Perky Pat genetic package (outgoing, friendly, and smart) soon became a best seller leading to a generation of cute children and annoying adults.
