A gay gene which causes homosexuality has not been identified. Factors other than genetics may have a significant influence on a person's sexual orientation but to date no conclusive evidence has been found for a position on either side.
- Dr. Collins succinctly reviewed the research on homosexuality and offers the following: "An area of particularly strong public interest is the genetic basis of homosexuality. Evidence from twin studies does in fact support the conclusion that heritable factors play a role in male homosexuality. However, the likelihood that the identical twin of a homosexual male will also be gay is about 20% (compared with 2-4 percent of males in the general population), indicating that sexual orientation is genetically influenced but not hardwired by DNA, and that whatever genes are involved represent predispositions, not predeterminations."

- Regarding the contributions of genetics to areas such as homosexuality, Dr. Collins concluded, "Yes, we have all been dealt a particular set of cards, and the cards will eventually be revealed. But how we play the hand is up to us." [2]
