Through research done by Michael J. Poulin of the Department of Psychology at the University at Buffalo, niceness is linked to the hormones oxytocin, vasopressin, and their receptor genes. By using his work about the most favorable repressor gene for these two hormones, the gene will be found and removed from human cheek cells. The gene will be removed with a restriction enzyme. The sections cut will be placed into a genome library.
