In 2010 scientists in Binghamton, NY discovered that men and women with the 7R+ variant of the DRD4 gene were more likely to be engaged in acts of infidelity. When interviewed as to whether or not these people were destined to commit adultery, scientists said that two factors determine behavior, genetics and the environment. A genetic predisposition did not remove a person’s ability to choose how to behave. In 1993 geneticist Dean Hamer found a link between the XQ28 chromosome band and homosexuality. A 1999 Canadian study disputed the claims. Is it dishonesty when people take such findings and on the one hand claim the ability to choose behavior, yet on the other hand claim the inability to choose because they were “born that way?” Genetic predisposition may be biologically determined but does it really remove the freedom to choose?
