I believe that a person’s sexual orientation is determined by a complex interaction between nature and nurture. Both of the person’s genetics and environment play an equally crucial role in forming who he or she is. This should not be limited to only personality traits and behaviors, but sexual preferences as well. There has been an abundant amount of research that prove the biological basis of sexual orientation. One such study was done by J. Michael Bailey and Richard Pillard on twins. They discovered that “52% of [identical] twins were both self-identified as homosexuals, 22% of [fraternal] twins were so, and only 5% of non-related adopted brothers were so” (Johnson 5). These results indicate that genes are linked to sexual preferences.
